This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
the sum of 8 and 4 times a number is 36
five times the sum of a number and 8 is -15.
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
A perfect number is the sum of its divisors; for example 6 is a perfect number because the sum of its divisors is 6 (1 + 2 + 3). The sum of the divisors of 8 is 7 (1 + 2 + 4), so 8 is not a perfect number.
Do this in reverse. The sum of -1 and -1 is -1+-1=-2 The difference of -6 and -6 is -6-(-6)=-6+6=0 0 increased by -2 is 0+-2=-2 The sum of 10 and -2 is 10+-2=8 Translation: 8

It is another whole number.
There can be no number with an odd sum of 8 because 8 is not odd!
N - 8
50 x 1.08 = 54
s= -8 + n, or s=n - 8, where s is the sum and n is the number
8 + S
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
The sum of the first 8 odd numbers is 64.
