Question type: Mathematical calculation
Solution:
(2.5-0.1)*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*(3.4-0.1)
=2.4*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*(3.4-0.1)
=2.4*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*3.3
=12+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*3.3
=12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*3.3
=12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+5.6*2+5*2*2*3.3
=12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+5*2*2*3.3
=12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+10*2*3.3
=12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+20*3.3
=12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
=33+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
=41.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
=43+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
=45.7+1.7+17+8.4+5+2.7+6.3+11.2+66
=47.4+17+8.4+5+2.7+6.3+11.2+66
=64.4+8.4+5+2.7+6.3+11.2+66
=72.8+5+2.7+6.3+11.2+66
=77.8+2.7+6.3+11.2+66
=80.5+6.3+11.2+66
=86.8+11.2+66
=98+66
=164
Answer:(2.5-0.1)*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*(3.4-0.1)=164
