Squaring Tricks
Squaring a number ending with 6
We can very eaisly calculate the square of a number ending with 6.
Let n6 be a number where n is an integer.
STEP 1: Subtract 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: Add the output of STEP 2 from STEP 3.
Example 1: Find square of 36?
STEP 1: (36 - 1 =35)
STEP 2: $(35)^2=1225$
STEP 3: (36 + 35 =71)
STEP 4: 1225 + 69 = 1296
Example 2: Find square of 336?
STEP 1: (336 - 1 =335)
STEP 2: $(335)^2=112225$
STEP 3: (336 + 335 =671)
STEP 4: 112225 + 671 = 112896
