计算能简算的要简(要过程)算105×36-309 (20.06-60.01÷8.5)×15 36×101 64.8×99+64.8

帮帮忙计算能简算的要简(要过程)计算能简算的要简(要过程)算105×36-309 (20.06-60.01÷8.5)×15 36×101 64.8×99+64.8
105×36-309
=100*36+5*36-309
=3600+180-309
=3471
(20.06-60.01÷8.5)×15
=20*15+0.06*15-(60*15+0.01*15)/8.5
=300+0.9-(900+0.15)/8.5
=300.9-105.9
=195
36×101
=36*100+36*1
=3600+36
=3636
64.8×99+64.8
=64.8*(99+1)
=64.8*100
=6480
