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#
