The answer is #105#

Explanation:

Recall the common acronym for the order of operations: PEMDAS.

P–Parentheses
E–Exponents
M–Multiplication
D–Division
A–Addition
S-Subtraction

In evaluating an expression, you begin by working within parentheses, then evaluate exponents, multiply and divide at the same time (moving from left to right), and lastly, add and subtract at the same time (again, from left to right).

In this problem, simply add within the parentheses, producing:

#7*15#

Multiplying these numbers gives the answer, #105#.
