If 2+3=8, 3+7=27, 4+5=32, 5+8=60, what is the value of 6+7?
This is a practice of OVERLOADING. That is, the "+" sign now has another operation that it performs. Let's find our what that is:
GIVEN Actually
2+3 = 8 2*4=8
3+7=27 3*9=27
4+5-32 4*8=32
5+8=60 5*12=60
6+7= ??
Now, notice the second multiplicand ( that 4, 9, 8, an 12 ) are 1, 2, 3, and 4 more than 3.7.5.and 8.
So, we add 5 to 7 to get 12. 6+12 = 72.
6+7 = 72
