Question

Найди произведения. Для этого представь двузначные числа в виде суммы разрядных слагаемых? 22*3 34*2 33*3 25*3 28*3 33*2 23*3 42*5 43*2 24*3 31*4 36*3 Образец: 23*4=(20+3)*4+20*4+3+80+12+92

Answer 1

(20+2)*3+(30+4)*2+(30+3)*3+(20+5)*3+(20+8)*3+(30+3)*2+(20+3)*3+(40+2)*5+(40+3)*2+(20+4)*3+(30+1)*4+(30+6)*3

Answer 2

22*3 = (20+2)*3 + 20*3 + 2 = 60 + 60 + 2 = 122

34*2 = (30+4)*2 + 30*2 + 4 = 68 + 60 + 4 = 132

33*3 = (30+3)*3 + 30*3 + 3 = 99 + 90 + 3 = 192

25*3 = (20+5)*3 + 20*3 + 5 = 75 + 60 + 5 = 140

28*3 = (20+8)*3 + 20*3 + 8 = 84 + 60 + 8 = 152

33*2 = (30+3)*2 + 30*2 + 3 = 66 + 60 + 3 = 129

23*3 = (20+3)*3 + 20*3 + 3 = 69 + 60 + 3 = 132

42*5 = (40+2)*5 + 40*5 + 2 = 210 + 200 + 2 = 412

43*2 = (40+3)*2 + 40*2 + 3 = 86 + 80 + 3 = 169

24*3 = (20+4)*3 + 20*3 + 4 = 72 + 60 + 4 = 136

31*4 = (30+1)*4 + 30*4 + 1 = 124 + 120 + 1 = 245

36*3 = (30+6)*3 + 30*3 + 6 = 108 + 90 + 6 = 204

So the products of the given numbers are:

122, 132, 192, 140, 152, 129, 132, 412, 169, 136, 245, 204.
