- \(1.54-0.5\cdot1.3=1.54-0.65=0.89\).
- \(0.2\cdot2.6-3.89=0.52-3.89=-3.37\).
- \(3.54+0.5\cdot1.3=3.54+0.65=4.19\).
- \((3.7-5.9):0.4=-2.2:0.4=-5.5\).
- \((3.7-5.2)\cdot0.8=-1.5\cdot0.8=-1.2\).
- \(2.81\cdot3.4-5.66=9.554-5.66=3.894\).
- \(-7.1+7.68:1.2=-7.1+6.4=-0.7\).
- \(-8.8+6.5\cdot1.6=-8.8+10.4=1.6\).
- \((2.3-5.9):40=-3.6:40=-0.09\).
- \(7.84-0.7\cdot1.2=7.84-0.84=7\).
