Integer Combat Answer Key
Integer Combat
SIDE A KEYS: ADDITION & SUBTRACTION
ADMIN MODE
RD 1: ADDITION SOLVED
\(-14 + (-25) + 32 = -7\)
Logic: 1) \(-14 + (-25) = -39\) (Same signs = add).
2) \(-39 + 32 = -7\) (Diff signs = subtract).
Error Tip: Watch for student adding absolute values across signs incorrectly to get \(-71\).
ANSWER:
-7
RD 2: SUBTRACTION SOLVED
\(18 - (-12) - 45 = -15\)
Logic: 1) \(18 - (-12) = 18 + 12 = 30\) (Double negative = add).
2) \(30 - 45 = -15\) (Subtract larger = negative).
Error Tip: Check if student simplified as \(18 - 12 - 45 = -39\).

-15

RD 3: MULTIPLY SOLVED
\(-3(4)(-8) = 96\)
Logic: 1) Multiply left-to-right: -3(4) = -12.
2) Multiply: -12(-8) = 96.
Rule: Parentheses mean multiplication. Two negatives multiply to a positive.
ANSWER:
96
RD 4: DIVISION SOLVED
\(-120 \div (-3) \div (-5) = -8\)
Logic: 1) Divide: -120 / (-3) = 40.
2) Divide: 40 / (-5) = -8.
Sequential Rule: Must work strictly left-to-right on multi-integer division!

-8
