What is mental math in times 3 digits like 8times25times23?
Mental math is a method of performing calculations using only your mind, without the use of a calculator or writing anything down. To calculate the product of three-digit numbers like 8 times 25 times 23, you can break the calculation into smaller, more manageable steps. Here's how you can approach it:
Step 1: Multiply 8 by 25:
To multiply 8 by 25, you can multiply 8 by 10 and then multiply the result by 2. Here's the breakdown:
8 x 10 = 80
80 x 2 = 160
Step 2: Multiply the result by 23:
Now, you have the result from step 1, which is 160. To multiply it by 23, you can use the distributive property of multiplication. Multiply 160 by 20 and then multiply it by 3. Here's the breakdown:
160 x 20 = 3200
3200 x 3 = 9600
Therefore, 8 times 25 times 23 is equal to 9600.
