Answer 2

0.89×100.1 5.83×2+4.27×2 4.2×99+4.2
=0.89100+0.1）
=0.89×100+0.89×0.89 =10×2
=89.089 =20

Answer 3

3.45*0.6*2.8=3.45×2.8×0.6=5.796

4.02＋5.4＋0.98
=4.02+0.98+5.4
=5+5.4
=10.4
5.17－1.8－3.2
=5.17-（1.8+3.2）
=5.17-5
=0.17

13.75－(3.75＋6.48)
=13.75-3.75-6.48
=3.52

33*145+33*55
=(145+55)*33
=200*33
=6600

369*136-36*369
=100*369
=36900

193*51+193*49
=100*193
=19300

25*32
=25*4*8
=800

79*16+79*78+79*6
=(16+78+6)*79
=100*79
=7900

25*32
=25*4*8
=800

193*51+193*49
=100*193
=19300

369*136-36*369
=100*369
=36900

33*145+33*55
=(145+55)*33
=200*33
