LEVEL 1: BASIC OPERATIONS
01
\(-15 + (-8) = -23\)
Sum of two negatives: add absolute values, keep negative sign.
02
\(12 - (-19) = 31\)
Subtracting a negative is adding: \(12 + 19 = 31\).
03
\(-7 \times 9 = -63\)
Negative multiplied by positive results in negative product.
04
\(-56 \div (-8) = 7\)
Dividing negative by negative yields a positive quotient.
05
\(-24 + 37 = 13\)
Find difference of absolute values: \(37 - 24 = 13\). Keep sign of larger absolute value.
06
\(-18 - 15 = -33\)
Rewrite as addition: \(-18 + (-15) = -33\).
07
\(-12 \times (-6) = 72\)
Multiplying two negatives yields a positive product.
08
\(84 \div (-7) = -12\)
Dividing positive by negative yields a negative quotient.
LEVEL 2: WORD PROBLEMS
09
\(-150 - 85 = -235\)
Starts below sea level (\(-150\)), descends (\(-85\)). Final depth is \(235\) ft below.
10
\(-12 + 19 = 7\)
Initial temp (\(-12^\circ\)), rises (\(+19\)). Final temp is \(7^\circ\text{C}\).
11
\(-45 + 120 = 75\)
Overdrawn balance (\(-\$45\)), deposit (\(+\$120\)). Final balance is \(\$75\).
12
\(-25 \times 4 = -100\)
Loss of \(25\) points per hazard times \(4\) incidents equals \(-100\) points.
