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.

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
