Sean says that to add a number to –100 and still have –100 is to add zero. candice says that she can add two numbers to –100 and still have –100. who is correct and why? sean is correct because adding any numbers other than zero will result in a different number. candice is correct because if the two numbers total 100, then the sum will be –100. they are both correct because adding two numbers that are opposites is equivalent to adding zero. neither is correct because adding any number to –100 will result in a different number.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
