STEP 1: Square first digit number.If square of a number is one digit then put 0 before the square of a number.

STEP 2: Square second digit number.If square of a number is one digit then put 0 before the square of a number.

STEP 3: Put together the STEP 1 and STEP 2.

STEP 4: Now, multiply the two digits and double your product, adding 0 to the end.

STEP 5: Add STEP 3 and STEP 4,we will get the result.

Example 1: Find square of 31?

STEP 1: $(3)^2=09$

STEP 2: $(1)^2=01$

STEP 3: 0901

STEP 4: $ 3\times 1 = 3, 3\times 2=6,60$

STEP 5: $0901+60=961$

Example 2: Find square of 82?

STEP 1: $(8)^2=64$

STEP 2: $(2)^2=04$

STEP 3: 6404

STEP 4: $ 8\times 2 = 16, 16\times 2=32,320$

STEP 5: $6404+320=6724$

Example 3: Find square of 64?

STEP 1: $(6)^2=36$

STEP 2: $(4)^2=16$

STEP 3: 3616

STEP 4: $ 6\times 4 = 24, 24\times 2=48,480$

STEP 5: $3616+480=4096$
