if i have understood your question correctly by estimation 23=20 , 46=50 and 79=80
adding the estimated values of 23 and 46 you get 70 which doesn't tally with the estimated value of the sum

Estimated
23 is about 20
46 is about 50
79 is about 80
Sum is 150

23 + 46 + 79 = 148, therefore we are really close.
