B. In a subtraction formula, it is known that the sum of the minuend, the minuend and the difference is 100, so what is the minuend?
Reference answer:
1, ① 30+ 16 = 46 (pieces) 46-4 = 42 (pieces)
②30- 16 = 14(a) 14×3 = 42(a)
③200-96 = 104(page) 104÷8 = 13(page)
④ 200-96 = 104 (page) 104-96 = 8 (page)
⑤ 10× 4 = 40 (years old) 40+3 = 43 (years old)
2.a, train of thought analysis: Because there are four gaps between 1-5 floors, there are four 20 floors from 1 floor to the fifth floor, that is, 80 floors.
