A math worksheet on relative numbers in eighth grade is always beneficial for students. These math exercises on relative numbers involve the following concepts:
- comparison and addition of relative numbers.
Exercise 1:
Compare the following relative numbers:
-3 …… -4 ; 0 …..-8 ; -23 ……14,2 ; -12 ….. -16 ; -3,1 ….. -2,923
Exercise 2:
Arrange the following relative numbers in ascending order: -18 ; -2 ; 2 ; -20 ; -3 ; -1 ; 28 : -2,5
Exercise 3:
Julien plays a video game, whose hero collects (or loses!) gold coins. He already has many pieces. He does two games a day. Each evening, he fills in a table summarizing his wins and losses: To go faster, Julian decides to replace wins 10 by (+ 10), loses 3 by (- 3).
The balance of the 1st day can then be written: (+ 10) + (- 3).
Complete the balance column of the table below and then the last column of the table above.
| 1st part | Part 2 | Balance sheet | Other writing | |
| 1st day | +10 | – 3 | wins 7 | (+ 10) + (-3) = |
| Day 2 | – 11 | + 7 | ||
| Day 3 | – 8 | – 7 | ||
| Day 4 | + 10 | + 5 | ||
| Day 5 | + 10 | – 15 | ||
| Day 6 | + 7 | – 7 |
Application:
Complete:
(+ 8) + (+ 2) = …. (- 7) + (+ 5) = …. (- 4) + (- 6) = … (- 4) + (+ 7) = ….
