Sample questions
-
What is 15 / 5 x 8 / 6?
4. Start at the left with the first two numbers, 15 / 5 = 3:
15 / 5 x 8 / 6 = 3 x 8 / 6
Continue with the next two numbers, 3 x 8 = 24:
3 x 8 / 6 = 24 / 6
Finish up with the last two numbers:
24 / 6 = 4
-
Evaluate –10 x 2 x –3 / –4.
–15. The same procedure applies when you have negative numbers (just make sure you use the correct rule for multiplying or dividing by negative numbers). Start at the left with the first two numbers, –10 x 2 = –20:
–10 x 2 x –3 / –4 = –20 x –3 / –4
Continue with the next two numbers, –20 x –3 = 60:
–20 x –3 / –4 = 60 / –4
Finish up with the last two numbers:
60 / –4 = –15
Practice questions
-
Find 18 / 6 x 10 / 6.
-
Evaluate 20 / 4 x 8 / 5 / –2.
-
12 / –3 x –9 / 6 x –7 = ?
-
Solve –90 / 9 x –8 / –10 / 4 x 15.
-
18 / 6 x 10 / 6 = 5.
Divide and multiply from left to right:
18 / 6 x 10 / 6
= 3 x 10 / 6
= 30 / 6 = 5
-
20 / 4 x 8 / 5 / –2 = –4.
20 / 4 x 8 / 5 / –2
= 5 x 8 / 5 / –2
= 40 / 5 / –2
= 8 / –2 = –4
-
12 / –3 x –9 / 6 x –7 = –42.
12 / –3 x –9 / 6 x –7
= –4 x –9 / 6 x –7
= 36 / 6 x –7
= 6 x –7 = –42
-
–90 / 9 x –8 / –10 / 4 x –15 = 30.
–90 / 9 x –8 / –10 / 4 x –15
= –10 x –8 / –10 / 4 x –15
= 80 / –10 / 4 x –15
= –8 / 4 x –15
= –2 x –15
= 30
