Question

write any two decimal numbers and find their sum and difference
​

Answer 1

Answer:

Students learn to estimate the sum or difference of two decimals by first rounding each decimal to the nearest whole number, then adding or subtracting. For example, to estimate the sum of 4.94 and 2.185, round 4.94 up to 5, and round 2.185 down to 2, to get 5 + 2, which equals 7.
