Column A
1. (-4) × (-7) =
2. (-11) + (+4) =
3. (-108) ÷ (-3) =
4. (+27) – (-14) =
5. (-28) + (-15) =
Column B
+36
+41
43
+28
-7
ANSWER:
1. (-4) × (-7) =
- they are both negative so the answer should be positve.
- Negative × negative = [tex]\blue{positive}[/tex]
let's multiply
(-4)[tex]\times[/tex] (-7) = positive(+) 28
- so his answer is +28 because we multiply (-4) and (-7).
2. (-11) + (+4) =
Let's add
(-11) + (+4) = [tex]\red{-7}[/tex]
- The answer is [tex]\red{-7}[/tex] because (-11) + (+4) = [tex]\red{-7}[/tex] .
3. (-108) ÷ (-3) =
They are both negative so the answer should be positive.
let's divide
(-108) ÷ (-3) = [tex]\red{+36}[/tex]
- The answer is [tex]\blue{+36}[/tex] because (-108) ÷ (-3) = [tex]\red{+36}[/tex] .
4. (+27) – (-14) =
let's subtract
(+27) - (-14) = [tex]\red{+41}[/tex]
- The answer is [tex]\red{+41}[/tex] because (+27) - (-14) = 41.
5. (-28) + (-15) =
let's add
(-28) + (-15) = [tex]\red{-43}[/tex]
- The answer is [tex]\red{-43}[/tex] because (-28) + (-15) = [tex]\red{-43}[/tex] .
