The correct expression is:
153*80 - 153*47 - 153*33

Answer:
zero

Explanation:
1- We can note that 153 is common in the three terms. Therefore, we can take 153 as a common factor. This will give us:
153(80-47-33)

2- We resolve the operations within the parentheses. This will give us:
153(33-33)
which is equivalent to:
153(0)

3- Finally, we know that any number multiplied by a zero gives a zero. Therefore:
153*0 = zero

Hope this helps :)
