Work: Calculate the value of equation (1.8-0.1)+(1.1-0.1)+(1.4-0.1)+(4.1-0.1)*2+(1.7-0.1)*2+(3.5-0.1)*2+(2.1-0.1)*2 .
Question type: Mathematical calculation
Solution:
(1.8-0.1)+(1.1-0.1)+(1.4-0.1)+(4.1-0.1)*2+(1.7-0.1)*2+(3.5-0.1)*2+(2.1-0.1)*2
=1.7+(1.1-0.1)+(1.4-0.1)+(4.1-0.1)*2+(1.7-0.1)*2+(3.5-0.1)*2+(2.1-0.1)*2
=1.7+1+(1.4-0.1)+(4.1-0.1)*2+(1.7-0.1)*2+(3.5-0.1)*2+(2.1-0.1)*2
=1.7+1+1.3+(4.1-0.1)*2+(1.7-0.1)*2+(3.5-0.1)*2+(2.1-0.1)*2
=1.7+1+1.3+4*2+(1.7-0.1)*2+(3.5-0.1)*2+(2.1-0.1)*2
=1.7+1+1.3+4*2+1.6*2+(3.5-0.1)*2+(2.1-0.1)*2
=1.7+1+1.3+4*2+1.6*2+3.4*2+(2.1-0.1)*2
=1.7+1+1.3+4*2+1.6*2+3.4*2+2*2
=1.7+1+1.3+8+1.6*2+3.4*2+2*2
=1.7+1+1.3+8+3.2+3.4*2+2*2
=1.7+1+1.3+8+3.2+6.8+2*2
=1.7+1+1.3+8+3.2+6.8+4
=2.7+1.3+8+3.2+6.8+4
=4+8+3.2+6.8+4
=12+3.2+6.8+4
=15.2+6.8+4
=22+4
=26
Answer:(1.8-0.1)+(1.1-0.1)+(1.4-0.1)+(4.1-0.1)*2+(1.7-0.1)*2+(3.5-0.1)*2+(2.1-0.1)*2=26
