What is 254.91 + 26.845?

Explanation:
When adding decimals, line up the decimal points so each place value (tenths, hundredths, thousandths) is in the correct column. Since one number has three digits after the decimal and the other has only two, pad the shorter one with a trailing zero: 254.910 and 26.845. Add the parts separately: 0.910 + 0.845 = 1.755, and 254 + 26 = 280. Combine them to get 281.755. The result has three decimal places, matching the maximum decimals in the inputs, so the sum is 281.755.
