Question

match the values to the expressions in the match table.
12 -12 neither
3(-4) □ □ □
3+9 □ □ □
10+2 □ □ □
6+-18 □ □ □
96÷-8 □ □ □
-20+32 □ □ □

Explanation:

Step1: Calculate \(3(-4)\)

Multiply 3 and -4: \(3\times(-4)= -12\)

Step2: Calculate \(3 + 9\)

Add 3 and 9: \(3 + 9 = 12\)

Step3: Calculate \(10 + 2\)

Add 10 and 2: \(10 + 2 = 12\)

Step4: Calculate \(6 + (-18)\)

Add 6 and -18: \(6 + (-18)= -12\)

Step5: Calculate \(96\div(-8)\)

Divide 96 by -8: \(96\div(-8)= -12\)

Step6: Calculate \(-20 + 32\)

Add -20 and 32: \(-20 + 32 = 12\)

Answer:

• For \(3(-4)\): Check the box under \(-12\)
• For \(3 + 9\): Check the box under \(12\)
• For \(10 + 2\): Check the box under \(12\)
• For \(6 + (-18)\): Check the box under \(-12\)
• For \(96\div(-8)\): Check the box under \(-12\)
• For \(-20 + 32\): Check the box under \(12\)
