Estimate Products

In this topic, we learn to estimate products by rounding and front-end estimation.

Topic: Round to Estimate Products

  • We can estimate the products whenever an exact product is not required

  • To estimate products, round the number to the highest place

  • To estimate 7 x 345, round 345 to the nearest hundred and multiply

Topic: Front End Estimation

  • We can estimate the products whenever an exact product is not required

  • The front end estimation uses the "front" digit and zeros the other digits to estimate

  • 7 x 352 = 7 x 300 = 2,100
