Step-by-Step Solution
Rewrite subtraction as addition of the opposite: 12 − 17 = 12 + (−17). Different signs, so subtract: 17 − 12 = 5. Keep the sign of the larger absolute value (negative 17), giving −5.
Answer: B) −5
Compute: 12 − 17 (type a number, including the sign if negative)

Key idea: Adding integers — same sign
When two integers have the **same sign**, add their absolute values and keep the sign. So 4 + 3 = 7 (both positive → result positive), and (−4) + (−3) = −7 (both negative → result negative). On the number line: same sign means you keep moving in the same direction.
