The document provides a step-by-step method for calculating the square roots of numbers between 10 and 99. It details the process for different ranges of numbers, including examples for 10 to 19, 20 to 29, and 30 to 39. The method involves multiplying the ones digit, adding relevant values, and combining results to find the square root.

1. How to Get the
Square Roots
of the Numbers
from
10 to 99???
Watch and look to this video 

2. Square Roots from 10 to 19
• 102
tens
ones
1. Multiply first the ones. 0 x 0 = 0
This would be the last digit of our answer.
2. Add the number which is 10 to its ones digit (0).
10 + 0 = 10
This would be the first digits of our answer.
3. Combine the answer in 2 and 1. 100
So the answer is 100.

3. Square Roots from 10 to 19
• 112
tens
ones
1. Multiply first the ones. 1 x 1 = 1
This would be the last digit of our answer.
2. Add the number which is 11 to its ones digit (1).
11 + 1 = 12
This would be the first digits of our answer.
3. Combine the answer in 2 and 1. 121
So the answer is 121.

4. Do the same steps from numbers 12 to 13


5. Square Roots from 10 to 19
• 142
tens
ones
1. Multiply first the ones. 4 x 4 = 16
We will only use the ones digit (6) for the
ones digit of our answer.
2. Add the number which is 14 to its ones digit (4) and
to the tens digit in #1.
14 + 4 + 1 = 19
This would be the first digits of our answer.
3. Combine the answer in 2 and 1. 196
So the answer is 196.

6. Do the same steps in getting the square
root of 14 from numbers 15 to 19 

7. Square Roots from 20 to 29
• 202
tens
ones
1. Multiply first the ones. 0 x 0 = 0
This would be the last digit of our answer.
2. Multiply the number which is 20 to its tens digit (2).
20 x 2 = 40
Then add it to the sum of your ones (0 + 0 = 0).
40 + 0 = 40
This would be the first digits of our answer.
3. Combine the answer in 2 and 1. 400
So the answer is 400.

8. Do the same steps in getting the square
root of 20 from numbers 21 to 23 

9. Square Roots from 20 to 29
• 242
tens
ones
1. Multiply first the ones. 4 x 4 = 16
We will only use the ones digit (6) for the
ones digit of our answer.
2. Multiply the number which is 24 to its tens digit (2).
24 x 2 = 48
Then add it to the sum of your ones (4 + 4 = 8) and to
the tens digit in #1.
48 + 8 + 1 = 57
This would be the first digits of our answer.
3. Combine the answer in 2 and 1. 576
So the answer is 576.

10. Do the same steps in getting the square
root of 24 from numbers 25 to 29 

11. Square Roots from 30 to 39
• 302
tens
ones
1. Multiply first the ones. 0 x 0 = 0
This would be the last digit of our answer.
2. Multiply the number which is 30 to its tens digit (3).
30 x 3 = 90
Then add it to the product of your tens and ones digit
(3 x 0 = 0).
90 + 0 = 90
This would be the first digits of our answer.
3. Combine the answer in 2 and 1. 900
So the answer is 900.

12. Do the same steps in getting the square
root of 30 from numbers 31 to 33 

13. Square Roots from 30 to 39
• 342
tens
ones
1. Multiply first the ones. 4 x 4 = 16
We will only use the ones digit (6) for the
ones digit of our answer.
2. Multiply the number which is 34 to its tens digit (3).
34 x 3 = 102
Then add it to the product of your tens and ones
digit(3 x 4 = 12) and to the tens digit in #1.
102 + 12 + 1 = 115
This would be the first digits of our answer.
3. Combine the answer in 2 and 1. 1156
So the answer is 1156.

14. Do the same steps in getting the square
root of 34 from numbers 35 to 39 

15. Note: GETTING THE SQUARE ROOTS
FROM 40 TO 99 ARE JUST THE SAME
IN GETTING THE SQAURE ROOTS IN
30 TO 39 !!
