As division is just the opposite of multiplication, the rules for dividing by integers are the same as the rules for multiplying integers. Let's recap them:
$20\div5=4$20÷5=4
$200\div20=10$200÷20=10
$20\div\left(-5\right)=-4$20÷(−5)=−4
$\left(-49\right)\div7=-7$(−49)÷7=−7
$\left(-20\right)\div\left(-5\right)=4$(−20)÷(−5)=4
$\left(-60\right)\div\left(-3\right)=20$(−60)÷(−3)=20
Some division questions are written as word problems, which we can write as algebraic expressions.
Evaluate: A number $n$n is divided by $-6$−6 to give $4$4. What is the value of $n$n?
Think: That expression means $n\div\left(-6\right)=4$n÷(−6)=4
Do: $n=-24$n=−24
Evaluate: A number, $n$n, is divided by $-5$−5 to give $-4$−4. What is the value of $n$n?
