15-7×5

To solve the expression \(15 - 7 \times 5\), you should follow the order of operations, which states that you perform multiplication before subtraction.

1. First, calculate \(7 \times 5\): \[ 7 \times 5 = 35 \]

2. Next, subtract that result from 15: \[ 15 - 35 = -20 \]

So, \(15 - 7 \times 5 = -20\).
