-15 + x = 21
Add 15 to each side of the equation:
x = 36
36
The result will be positive in this case.

When 3 is added 5 times to a number the result is 15 if the number is 0, otherwise this is not true. However, the amount added to the number is always 15. Let's say the variable x is our number and y is the result, then x+3+3+3+3+3=y. You can add all the 3's together now. So you have x+15=y. Now if the starting number is 0, you have 15=y, so the result is 15.
90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.
15 is an integer, not a fraction. If you must, you can express it as a fraction as 15/1.Multiply the numerator (top) and the denominator (bottom) of this fraction by any non-zero integer. You will have an equivalent fraction.15 is an integer, not a fraction.

The original integer's value is increased by one - (15 + 1 = 16).
The result will be positive in this case.
It is: -2 because -2-15 = -10-7 => -17 = -17

To solve this set it up as an equation. Say x = some integer, so x + 15 = 10 times -3. x + 15 = -30, so x = -30 - 15 which means x = -45

15/3 = 5 5 is an integer.
It is divisibility by 3 and divisibility by 5.Divisibility by 3: the digital root of an integer is obtained by adding together all the digits in the integer, with the process repeated if required. If the final result is 3, 6 or 9, then the integer is divisible by 3.Divisibility by 5: the integer ends in 0 or 5.
A multiple is the result of multiplying a number by an integer. 5: 5, 10, 15, 20
An integer is a number, positive or negative. So 15 is an integer.
