Would you use mental math to solve 2984+1997+406? Explain?

3,000 + 2,000 + 400

To solve the expression 2984 + 1997 + 406 mentally, you can follow these steps:

1. Start by adding the hundreds place values:
- Add 2 + 1 + 0, which gives you 3.

2. Move on to the tens place values:
- Add 9 + 9 + 0, which gives you 18.

3. Finally, add the ones place values:
- Add 8 + 7 + 6, which gives you 21.

4. Put all of the results together to get the final answer:
- So, 2984 + 1997 + 406 = 3403.

By breaking down the problem into smaller steps, you can add the numbers mentally without relying on a calculator or written work.

Yes, you can use mental math to solve the addition problem 2984 + 1997 + 406. Here's how you can go about it:

1. Start by adding the units (ones) place of each number. In this case, it would be 4 + 7 + 6 = 17.

2. Since the sum is greater than 9, you carry over the digit in the tens place and add it to the sum of the tens places. In this case, the tens places are 8, 9, and 0. So, 8 + 9 + 0 = 17.

3. Again, the sum is greater than 9, so you carry over the digit in the hundreds place and add it to the sum of the hundreds places. In this case, the hundreds places are 9, 9, and 4. So, 9 + 9 + 4 = 22.

4. Finally, you add the thousands places, which are 2, 1, and 0. So, 2 + 1 + 0 = 3.

Putting it all together, the answer is 3203.

Using mental math for this addition problem involves breaking down the numbers into their place values and adding them up one place at a time. It helps to focus on one digit at a time and carry over any excesses when necessary.
