Answer:

cubing multiplication subtraction

Explanation:

to answer this question you need to know order of operation to know what to do first.

you can summarise it by the word PEMDAS (first letter for first operation)

P for parentheses "( )"

E for exponentiation "power"

M D for multiplication and division "×÷" (you can switch between them in order)

A S for addition and subtraction "+-" (you can switch between them in order)

so in this case exponentiation (cubing), then multiplication, then subtraction.


\\15-13 * 2^(3)\\


=15-13 * 8\\=15-104\\=-89
