Answer 1

Explicație:

2587+1899+578-1699=

4486+578-1699=

5064-1699=3365

10000-4567-1787+1285=

5433-1787+1285=

3646+1285=4931

(4567+4585)-(8100-5323)-899=

9152-2777-899=

6375-899=5476

9200-(7005-2683)-(1979+1867)=

9200-4322-3846=

4878-3846=1032

(8866-1987-4655)+(6400-2688)+4064=

2224+3712+4064=

5936+4064=10000

6010-(4285+3795-6287)-894+1111=

6010-1793-894+1111=

4217-894+1111=

3323+1111=4434

Baftă!
