To find the product of 3 and 122 using mental math, you can break it down into simpler steps:
1. Start by multiplying the rightmost digit of 122 (which is 2) by 3: 2 x 3 = 6.
2. Next, multiply the tens digit of 122 (which is 2) by 3, and since it's a tens digit, you need to multiply by 10 as well: 2 x 3 x 10 = 60.
3. Finally, multiply the hundreds digit of 122 (which is 1) by 3, and since it's a hundreds digit, you need to multiply by 100 as well: 1 x 3 x 100 = 300.
4. Add up the results from steps 1, 2, and 3: 6 + 60 + 300 = 366.
Therefore, 3 x 122 equals 366.
To find the answer to 3 multiplied by 122 using mental math, you can break down the calculation into simpler steps.
Step 1: Multiply 3 by 100 (the nearest hundred to 122) to get 300.
