2.3*99+2.3
=2.3*100
=230
28.125-1/8-3.7
=28-3.7
=24.3
(1/2-1/3+6/6)
=(3/6-2/6+6/6)
=(7/6)*18
=21
16*25*125
=4*25*4*125
=500*100=50000
101*93-93
=100*93
=9300

2.3*99+2.3 =2.3*100 =230 28.125-1/8-3.7 =28-3.7 =24.3 (1/2-1/3+6/6) =(3/6-2/6+6/6) =(7/6)*18 =21 16*25*125 =4*25*4*125 =500*100=50000 101*93-93 =100*93 =9300
