How can the order of precedence in this formula, =c12 c13*f4, be changed so that cells c12 and c13 are added together as the first operation that occurs?

How can the order of precedence in this formula, =C12+C13*F4, be changed so that cells C12 and C13 are added together as the first operation that occurs?

We must add a parenthesis.

from:  = C12+C13*F4
to: =(C12+C13)*F4

This is the same in Math, the order of operation is PEMDAS
Do first the operation with in the PARENTHESIS, then those that have EXPONENTS, then MULTIPLICATION, then DIVISION, then ADDITION, lastly SUBTRACTION.

Ithink your answer is b
