Question

How do you simplify `17g + g`?

Answer 1

The answer would be 18g.

Explanation:

Multiplying is just shortened adding. 17g is adding g 17 times. So, adding g 17 times and then adding another g would be adding g 18 times, resulting in `18g`.

Answer 2

Use the identity and distributivity properties of multiplication and addition to find:

`17g+g=18g`

Explanation:

Firstly using the multiplicative identity property of `1` we have:

`g = 1g`

So:

`17g+g = 17g+1g`

Then use the distributivity of multiplication over addition to find:

`17g+1g = (17+1)g = 18g`
