## How to Find a Square Root Without a Calculator

Contents

Using a calculator is a great way to find the square root of a number. It’s quick and easy and requires you to multiply the number by itself. A two by two table, for example, shows four blocks. You can also estimate the square-root by using the number’s unit digit. Then, divide that figure by your chosen square roots to get the average. Now, you can use your calculator to find the square-root of a number.

To find the square-root of a number, first divide the number into pairs. If the number is three, it would be 3 61. Then, look for the square that is the largest. It gives you the first part of the answer. Next, divide the number into two with the second half of the equation. Then, add the two halves together. This gives you the remainder. If you’ve found a negative or mixed number, the square-root method is the easiest way to find it.

You’ll see the result of your calculation is the square root of the number. But what if you don’t have a calculator? If this is the case, there are many ways to calculate the square-root of a number. Once you have calculated the value of a number, you’ll need to find the number’s arithmetic mean. Then, you’ll have to find its square-root.

## How to find a square root Overview

When finding the square root of a number you need to use a calculator, a computer, or a special method called the “Newton-Raphson Method”. You need a special calculator that can handle the big number and give the results in whether whole numbers or in decimal points.

## what is this calculator?

This calculator is called the “GDC TI-30X IIS”. It can round out numbers in whole points or in decimal points.
The GDC TI-30X IIS is a scientific and engineering calculator that can do it all for you!

This method is very complicated, so if you are planning to do this by hand it is recommended you get a calculator out.

## Instructions:

Step 1: Find the number whose square root you want to find. Let’s say we want to find the square root of “-9”.

Step 2: Use the index number finger rule to turn your number into scientific notation. Remember, if it is a positive exponent, you will move the decimal place to the left and if it is a negative exponent you will move the decimal place to the right.
“-9” = “.9899*10^-3”

Step 3: Divide the exponent in scientific notation by 2. We want to divide by 2 because when you divide the exponent by 2, you are taking 10^1 which equals one. This will help us simplify our work.

“-9” = “

## what is the formula?

-9 = 1.234510^1 Step 4: Simplify the number by dividing it by the divisor you got in step 3. 1.234510^1 = 12.345

Step 5: Think of a number that can be multiplied by the divisor without making the number greater than your original number. We can multiply by 10 with no problem because multiplying by 10 means adding a zero to your number. In this case, we will multiply by 10.

12.345*10 = 123.45

123.45 = 12.345*10^1
Thank you.
