Question: User: use quick way to calculate 250 into 32 into 10 . Write a step by step solution class 7
1. **State the problem:** Calculate the product of $250$, $32$, and $10$ quickly.
2. **Understand the multiplication:** We want to find $$250 \times 32 \times 10$$.
3. **Use the associative property of multiplication:** We can group the numbers in any order to make calculation easier.
4. **Group $250$ and $10$ first:**
$$250 \times 10 = 2500$$
5. **Now multiply the result by $32$:**
$$2500 \times 32$$
6. **Calculate $2500 \times 32$ by breaking $32$ into $30 + 2$:**
$$2500 \times 30 = 75000$$
$$2500 \times 2 = 5000$$
7. **Add the two products:**
$$75000 + 5000 = 80000$$
8. **Final answer:**
$$250 \times 32 \times 10 = 80000$$
This quick method uses grouping and breaking down numbers to simplify multiplication.
