Answer 1

Răspuns:

1 000 + 1 000 x 10 - 10 x100 + 100x10x0

1 000+10 000-1 000+0

11 000-1 000=10 000

10x10x10+100x100x100-1 000x1 000=

1 000+1 000 000-1 000 000=1 000

700 542-838x100-(990+3x1 000):5=

700 542-83 800-(990+3 000):5=

700 542-83 800-3 990:5=

700 542-83 800-798=

616 742-798=615 994
