Answer 1

on saturday 94,887 rode on local bus in staten island and 11,107 passengers rode on the express bus how many passengers rode on the two buses on saturday

#passengers on local bus + #passengers on express bus=

94,887+11,107=(94,000+11,000) + 887 + 107 = 105,000 + (880+100) + 7 + 7 =

105,000 + 980 + 14 = 105,000 + 994 = 105,000 + 1,000 - 6 = 106,000 - 6 = 105,994

It was all "give and take"!
