Answer 1

Răspuns:

4753 +1211=5964

b) 7600+2400 =10000 (7600-2400)=5200

6704 + 2203=8907

5170 + 2140 =7310 (5170-2140)=3030

12425 +13172=25597

16598 - 12173 =4425

745240 +120734 =865974

219176-109142 =110034

c) 1672 +2124 - 386=3410

17903 +12096 - 20992 =9007

145942–42921 +11111=114132

29788-19643-12000 = -1855
