Question

вычисли записав одно из чисел в развёрнутой форме 7 853+1 132=. 7853-1132=. 164 675+35212=. 164 675-35 212=​

Answer 1

7 853 + 1 132 = (7000 + 800 + 50 + 3) + (1000 + 100 + 30 + 2) =

(7000 + 1000) + (800 + 100) + (50 + 30) + (3 + 2) =

8000 + 900 + 80 + 5 =

8985

7853 - 1132 = (7000 + 800 + 50 + 3) - (1000 + 100 + 30 + 2) =

(7000 - 1000) - (800 - 100) - (50 - 30) - (3 - 2) =

6000 - 700 - 20 - 1 =

5279

164 675 + 35 212 = (100000 + 60000 + 4000 + 600 + 70 + 5) + (30000 + 5000 + 200 + 10 + 2) =

(100000 + 30000) + (60000 + 5000) + (4000 + 200) + (600 + 10) + (70 + 2) +

(5) =

130000 + 65000 + 4200 + 610 +

72 +

5 =

200087

164675 -35212 = (100000+60000+4000+600+70+5)-(30000+5000+200+10+2)=

(100000-30000)-(60000-5000)-(4000-200)-(600-10)-(70-2)-(5)=

70000-55000-3800-590-68-5=
