What I like to do it just round the numbers. 33 would go to 30. 76 would go to about 80. 30 times 70 equals about 2,100. Your answer should be somewhere around there.
Estimation: 30 x 80 = 2400 Method for Actual answer: (30 x 70) + (3 x 6) 2100 + 18 = 2118
To estimate 33 × 76 , round 33 to 30 and 76 to 80 . Then, multiply them to get 30 × 80 = 2400 , making the estimated product approximately 2400 .
