Numbers can go below zero too. Drag the sliders and watch two integers add together on a number line.
Try it: make B negative to see subtraction in action!
You already know natural numbers (1, 2, 3...) and whole numbers (0, 1, 2, 3...). Integers extend this further to include negative numbers: ...−3, −2, −1, 0, 1, 2, 3...
Counting numbers, starting from 1.
Natural numbers plus zero.
Whole numbers plus all negative numbers.
On a number line, numbers get bigger as you move right and smaller as you move left. Compare −7 and −2. Since −2 is to the right of −7 on the number line, −2 > −7
Which is greater: −10 or 3? Even though 10 is a "bigger" number, −10 is far to the left of zero, so 3 > −10
Solve: (−4) + (−6). Add the numbers and keep the negative sign: −10
Solve: (−8) + 5. Subtract the smaller from the bigger (8−5=3), and keep the sign of the bigger number: −3
Solve: 6 − (−4). Subtracting a negative is the same as adding: 6 + 4 = 10
Arrange 45,231, 8,900, and 102,450 in ascending order (smallest to largest).
8,900 < 45,231 < 102,450
Arrange 7,65,432, 98,765, and 8,05,000 in descending order (largest to smallest).
8,05,000 > 7,65,432 > 98,765
