Answer 1

a) Mai intai efectuam calculele din paranteza.

   123458 + 29387 - (42203-17123)=

   123458 + 29387 - 25080=

   152845 - 25080=127765

b) 287810 + 15875 = 303685

c) 20392 - 3799 + 23145

   16593 + 23145 = 39738

Answer 2

a)

1. 42.203 - 17.123 = 25.080

2. 123.458 + 29.387 = 152.845

3. 152.845 - 25.080 = 127.765

= 127.765

b)

802.724 - 514.914 = 287.810

287.810 + 15.875 = 303.685

= 304.685

c)

1. 5.158 + 15.234 = 20.392

2. 3.210 + 589 = 3.799

3. 20.392 - 3.799 = 16.593

4. 23.145 + 16.593 = 39.738

= 39.738
