Given :
Estimate the following 35789 + 3805
Explanation :
In order to estimate the numbers first we round off the numbers.
First number is 35789
Its digit at tens place is 8 that is greater than 5, so we will increase the digit at hundredth place by 1.
and replace each digit at tens and ones place by 0 to get the rounded off number.
Hence the rounded off number 35789 is 35800
and next number will be 3805 = 3800
By rounding of each digit to the nearest hundredth.
35700 + 3800 = 39500
