Answer 1

3254+146+169

=3400+169

=3569

4.27.25

=108.25

=2700

638+780.5-369:9

=638+3900-41

=4538-41

=4497

779:41.16.(425-249)

=779:41.16.186

=19.16.186

=304.186

=56544

25.5.4.27.2

=125.4.27.2

=500.27.2

=13500.2

=27000

28.64+28.36

=28.(64+36)

=2800

(42.43+43.57+43)-360:4

=(1806+2451+43)-360:4

=4300-360:4

=4300-90

=4210

Answer 2

a) = 3400 + 169 = 3569

b) = 108 x 25 = 2700

c) = 638 + 3900 - 369 : 9 = 4497

d) = 779 : 41 x 16 (435 - 249) = 56544

e) = 125 x 4 x 27 x 2 = 27000

f) = 1792 + 28 x 36 = 2800

g) = 43 x 100 - 90 = 4210
