Answer 1

5,24 -1,60-1,40=5.24-3=2.24
5,14+10,21-3,4=15.35-3.4=11.95
5,6-3,16+5,12=10.72-3.16=7.56
(7,10+3,5)-(1,6+2,3)=10.6-3.9=6.7
2,3-(1,20+2,9)-5,18=2.3-4.1-5.18= -6.98
1,3+1,4+1,5+1,6+1,7=2.7+1.5+1.6+1.7=4.2+1.6+1.7=5.8+1.7=7.5
1,2+2,3+3,4=3.5+3.4=6.9
7,8+1,6-2,3=9.4-2.3=7.1
9,10-3,5+5,7=14.8-4.5=11.3
