- Positive(+) times positive(+) is equal to positive
- Negative(-) times negative(-) is equal to positive
- Negative(-) times positive(+) is equal to negative
DIVIDING
- Positive(+) divided by positive(+) is equal to positive
- Positive(+) divided by negative(-) is equal to negative
- Negative(-) divided by positive(+) is equal to negative

Step-by-step explanation:
A=cost of 1 adult ticket
c=cost of 1 child ticket
so
9a+2c=252
and
c=a-6
sub a-6 for c
9a+2(a-6)=252
9a+2a-12=252
11a-12=252
add 12 both sides
11a=264
divide both sides by 11
a=24
sub back
c=a-6
c=24-6
c=18
adult ticket costs $24 and child ticket costs $18
