**How do you find the square of a 3 digit number?**

Calculating the square of 3 digit number quickly 1 Last digit = last digit of SQ (Z) 2 Second Last Digit = 2*Y*Z + carryover from STEP 1. 3 Third Last Digit 2*X*Z+ Sq (Y) + carryover from STEP 2. 4 Fourth last digit is 2*X*Y + carryover from STEP 3. 5 In the beginning of the result (the first digit) will be Sq (X) + any carryover from Step 4.

## What is a square number called?

When a number or integer (not a fraction) is multiplied by itself, the resultant is called a ‘Square Number’. For example, 3 multiplied by 3 is equal to 3-squared or 3 x 3 = 32.

## What are the two-digit square numbers?

The list of two-digit square numbers is 16, 25, 36, 49, 64 and 81. Squares of even numbers are even, i.e, (2n) 2 = 4n 2. Squares of odd numbers are odd, i.e, (2n + 1) 2 = 4 (n 2 + n) + 1. Since every odd square is of the form 4n + 1, the odd numbers that are of the form 4n + 3 are not square numbers.

**How do you find the last digit of a square root?**

STEP 1. Last digit = last digit of SQ (1) =1 STEP 2. Second Last Digit = 2*2*1 + any carryover from STEP 1= 4 STEP 3. Third Last Digit 2*4*1+ Square (2) + any carryover from STEP 2=8+4=12
