explain how to find 40x50 usine mental math?
To find the product of 40 and 50 using mental math, you can use the distributive property and break down the calculation into smaller, more manageable steps. Here's how you can do it:
Step 1: Recognize that 40 is the same as 4 multiplied by 10 (40 = 4 x 10).
Step 2: Multiply 4 by 10 mentally, which is 40.
Step 3: Now, multiply 40 by 50. Since 50 is equivalent to 5 multiplied by 10 (50 = 5 x 10), we can further simplify the calculation.
Step 4: Multiply 40 by 5 mentally, which is 200.
Step 5: Lastly, add a zero to the end of 200 since we are multiplying by 10. This gives you the final answer of 2000.
Therefore, the product of 40 and 50 is 2000.
4 times 5 = 20
Add two zeros.
