What this lesson shows
Fixes a mistake
24 ÷ 4 × 2 is 12, not 3. Multiply and divide share one step.
The worked example
The lesson works this one step by step: 24 ÷ 4 × 2. Then your kid tries one like it on paper.
The steps
- Not M before D
- × and ÷ share a step
- Left to right
Helping at home
Multiply and divide share one step, and so do add and subtract. Within a step, work left to right, in the order the signs come.
If your kid gets stuck
Same step? Go left to right.
