Explain how to estimate 368+231 two different ways

Sagot :

368+231=599    it is to round of 368 to the nearest hundreds
400+200=600    add 100 if the hundredth number is 5 and above and add 0 if its 4 and below...

FROM: Jehiel S. Estrebello :)
1: add first; 368+231+599
    then estimate; 599 to 600(hundreds), 599 to 600(tens)

2:estimate first; 400+200(hundreds)
   then add; 400+200=600
estimate first; 370+230(tens)
   then add; 370+230=600

hope that helps
