4×3-3=	25×4×3=	3.4+2.2=	14.2-4.2=
50÷2-0=	4-2.6=	2 8 + 3 8 =	5 7 - 1 7 =
1- 5 6 =	4 9 + 5 9 =	5 7 - 5 7 =	5 6 -0=

Answer 1

15×60=900	0.4+10.5=10.9	12÷4×0=0	1-0.4=0.6
4×3-3=9	25×4×3=300	3.4+2.2=5.6	14.2-4.2=10
50÷2-0=25	4-2.6=1.4	2 8 + 3 8 = 5 8	5 7 - 1 7 = 4 7
1- 5 6 = 1 6	4 9 + 5 9 =1	5 7 - 5 7 =0	5 6 -0= 5 6 ．
