Squaring Tricks
Squaring a number ending with 4
We can very eaisly calculate the square of a number ending with 4.
Let n4 be a number where n is an integer.
STEP 1: Add 1 to the given number.
STEP 2: By adding 1 to the number it will take a form of n5 pattern and now we have to square of n5 [By using squaring of a number ending with 5 method we can eaisly calculate the square of n5.].
STEP 3: Sum the original number and output of STEP 1.
STEP 4: Subtract the output of STEP 2 from STEP 3.
Example 1: Find square of 34?
STEP 1: 34 + 1 =35
STEP 2: $(35)^2=1225$
STEP 3: 34 + 35 =69
STEP 4: 1225 - 69 = 1156
Example 2: Find square of 334?
STEP 1: 334 + 1 =335
STEP 2: $(335)^2=112225$
STEP 3: 334 + 335 =669
STEP 4: 112225 - 669 = 111556
