# How To Find Square Roots Using A Calculator

##### Share

When you’re faced with a math problem that involves finding the square root of a number, your first instinct might be to panic. But don’t worry! Finding the square root of a number isn’t as scary as it sounds. In this article, you’ll learn how to find the square root of any number using a calculator. If you think about it, calculating square roots is kinda weird. How can we find something that is “half” of another value? You probably won’t be able to fully comprehend what we’re about to explain, but don’t worry – that won’t keep you from being able to find the square root of any number using a calculator.

**How To Do Square Root On Calculator?**

**1. The Square Root Of A Number:**

A square root is just a number that has the same numeric value as the number you’re trying to find a square root of. Let’s say you want to find the square root of 25. The easiest way to do this is by using your calculator.

**2. Adding With Respective Squares:**

To find the square root of a number, you first have to calculate its squares (we’ll talk more about that in a second). So how do we calculate squares? We can use addition and subtraction to calculate squares. Let’s see what happens when we add 25+126 and then subtract 125 from our final answer:

**3. What Do We Have Here:**

It was a little surprising at first, but it all makes sense when you think about it: Add the two squares together and then subtract one from that result! Remember, our goal is to subtract one from each side so that we will end up with our final answer:

**4. Subtracting One From Both Sides Doesn’t Always Give You Your Final Answer:**

You may have noticed a pattern with addition and subtraction: If you add a number to something and then subtract that number from your final answer, it doesn’t always give you your final answer. This is especially true in square roots.

**5. The Square Root Of 25 Is 6:**

The square root of 25 is six, but we didn’t calculate 25-6=21 as our final answer because when we subtracted one from both sides, we did not get less than zero on each side. Luckily for us, the calculator can detect if something is greater or smaller than 0 and will help us out by changing each side to be less than zero before subtracting one from it!

**Converting Numbers To Squares**

**1. Convert Weights To Squares**

The table below shows the conversion of each weight from pounds to kilograms and from kilograms to pounds. The numbers are listed horizontally and vertically, with the value on the left and the number of pounds or kilograms on the right.

**2. The Relative Number System**

What would happen if you wrote down a number but didn’t know how many units that number was? A great example of this is writing down a paper number in English instead of using its equivalent in centimeters. How would we find out how many inches this number is? Since we don’t know that, we can’t just subtract it from 100 to get an answer! Instead, we have to find our unit of measurement before we can figure out the distance in inches or centimeters! In math, we call this a fixed point: A point where you don’t need to know how far something is as long as you remember its unit of measure.

**3. Subtract One From Both Sides To Get The Square Root Of 25**

In the example below, we want to subtract 2 from both sides. There are two ways to subtract a number from another: You can try to find a number that is less than the number you want and add 2 to that, or you can subtract both numbers from zero. Either way, we want less than zero on one side and then add 2 on the other side for our final answer.

**4. Convert Lengths To Squares**

The table below shows some lengths in centimeters, inches, and millimeters converted into squares with each unit of measurement representing 100 squares. The numbers are listed horizontally and vertically (with 100 on the left), with 100 being equal to 1 square unit. In this example, there are four centimeters in one square unit (since they are all equal length) so we would multiply by 4! If a unit is not listed in your area of study (for instance: 5 feet tall is 3 feet high), pick a standard for your area of study based on practice or another teacher’s suggestions.

**5. Convert Volume To Square Units**

The table below shows the conversion of units of volume from cubic inches to cubic centimeters and vice versa. The numbers are listed horizontally and vertically, with the value on the left and the number of cubic inches or cubic centimeters on the right.

**6. Convert Lengths To Cubic Units**

The table below shows some lengths in centimeters, inches, and millimeters converted into cubes with each unit of measurement representing 100 square units. The numbers are listed horizontally and vertically (with 100 on the left), with 100 being equal to 1 cube unit. In this example, there are four centimeters in one square unit (since they are all equal length) so we would multiply by 4! If a unit is not listed in your area of study (for instance: 5 feet tall is 3 feet high), pick a standard for your area of study based on practice or another teacher’s suggestions.

**How To Find The Square Root Using Calculus**

**1. Evaluate The Incidental Digits**

If we take the first step in the process of finding a root, we need to solve the equation, which means that we must find all of its solutions (or roots). In this case, we have:

You can see that you can add zero to both sides, just like in any other algebraic equation. But instead of adding a negative number or subtracting a positive number from both sides, you will now add a positive number to both sides. This is because when solving for x, it is always necessary to add one square root unit (in our case 2) to every solution given by multiplying by x. This method is called evaluating the incidental digits. However, for us to do this, we must do something with the digits on either side of our equation. This method is called adding or subtracting an actual number from or from.

**2. Evaluate The Intrinsic Square Root**

Now that we have solved for, it’s time to eliminate one of those two numbers and make sure that 0<=x<=1. The easiest way to accomplish this goal is by using HCF (Hood Chord Factor). In our example:

Now we have x = 0.9921 and so our answer is 3.88886.

**3. Evaluate The Coefficient Of R/X**

This step is similar to the above two, but here we are asked to find the coefficient of. So instead of eliminating one number (i.e., r= ), we now consider that this may be valid in both cases (i.e., when ) and when it is not valid (i.e., when ). Using HCF again:

As before, we have after solving for our solution; however, we can see that the solutions are not equal because they have different coefficients. In this case, it will be necessary to apply another method that eliminates the possibility of using r in other equations: differentiation! Using differentiation for this equation:

**4. Evaluate Former Digits With Differentiation**

Once again, evaluate. It may help you to forget about r now because its potential use in other equations has been eliminated in Step 3 above. This step would involve adding or subtracting an actual value from each digit as shown below:

**Summary**

Finding the square root of a number is as easy as inputting the number and hitting “sqrt” or “root” on your calculator. If you’re given two numbers and asked to find the square root of the sum or difference of those numbers, you’ll have to add or subtract their square roots. If you’re given a number and asked to find the square root of that number using calculus, you’ll have to break down the number and solve the equations for it.
