Work: Calculate the value of equation 1+1.1+1.2+1.3+1.4+1.5+1.6+1.7+1.8+1.9 .
Question type: Mathematical calculation
Solution:
1+1.1+1.2+1.3+1.4+1.5+1.6+1.7+1.8+1.9
=2.1+1.2+1.3+1.4+1.5+1.6+1.7+1.8+1.9
=3.3+1.3+1.4+1.5+1.6+1.7+1.8+1.9
=4.6+1.4+1.5+1.6+1.7+1.8+1.9
=6+1.5+1.6+1.7+1.8+1.9
=7.5+1.6+1.7+1.8+1.9
=9.1+1.7+1.8+1.9
=10.8+1.8+1.9
=12.6+1.9
=14.5
Answer:1+1.1+1.2+1.3+1.4+1.5+1.6+1.7+1.8+1.9=14.5
