The Best Way to calculating
Hey there! Let's make math calculations easier with these cool tricks:
- Break down big numbers into smaller chunks
- Instead of 23 × 4, think (20 × 4) + (3 × 4)
- This makes mental math way easier!
- Use number relationships
- To multiply by 5, multiply by 10 and divide by 2
- Example: 24 × 5 = (24 × 10) ÷ 2 = 240 ÷ 2 = 120
- Practice estimation
- Round numbers to make them easier to work with
- Use this to check if your final answer makes sense
