سؤال 85

Work out 3 + (-2) * 5. Enter the value.

پاسخ درست

-7

توضیح

Multiplication is carried out before addition, so the two below zero is taken five times to give ten below zero, and adding three leaves the value seven below zero. Adding the three first and multiplying afterwards would give five, which rewrites the expression rather than evaluating it.
