What is the sum of 140, 80, and 30?

Explanation:
Adding these numbers is just combining their values by place value. Break them into hundreds and tens: 140 has 1 hundred and 4 tens, 80 has 8 tens, and 30 has 3 tens. Add the tens: 4 + 8 + 3 = 15 tens, which is 150. Add the hundreds: 1 hundred equals 100. Total is 150 + 100 = 250. You can also see it by grouping: 140 + 80 = 220, then 220 + 30 = 250. The sum is 250.
