Key concepts
3 concepts
- 1
Division helps us find how many equal groups are in a total, and a number line is a clear visual model for dividing integers.
- 2
When using a number line to divide integers, the number of jumps shows the quotient's magnitude, and the direction of the jumps helps determine its sign.
- 3
If the dividend and divisor have the same signs, the quotient will be positive; if they have different signs, the quotient will be negative.
