Question

6. What number added to 145 results in zero?

Answer 1

Answer:

$-145$

Step-by-step explanation:

Let n represent our required number.

We are asked to find the number that when added to 145 results in zero.

The number added to 145 would be $n+145$.

The number added to 145 results in 0 would be:

$n+145=0$

Let us solve for n.

$n+145-145=0-145$

$n=-145$

Therefore, $-145$ added to 145 results in 0.

Answer 2

The number is -145.
145 + -145 = 0
**
Adding -145 is the same as subtracting 145.
And as a bonus fact: adding 145 is the same as subtracting -145.
Addition and subtraction are really the same thing.
So are multiplication and division.
