Question

rounding 738+56 using mental math

Answer 1

738+56=794

round-3(794)=1000

Answer 2

Given: 738+56  

When you round a number to the nearest thousand, look at the digit at the hundreds place.

If the digit is greater than or equal to 5, round it up.  If the digit is lesser than 5, round it down.

Here, 740>738>730 and 60>56>50, so 800>738+56>780

Thus, the value of the sum, 738+56, is somewhere in between 800 and 780.

So, the sum is rounded up to 1000.

The answer is: 1000
