六年級(jí)上冊(cè)數(shù)學(xué)簡(jiǎn)便例子演示17×62+62×63
解題思路:四則運(yùn)算規(guī)則(按順序計(jì)算,先算乘除后算加減,有括號(hào)先算括號(hào),有乘方先算乘方)即脫式運(yùn)算(遞等式計(jì)算)需在該原磨歷則前提下進(jìn)行
解題過程:
17×62+62×63
=（17+63）×62
=80×62
=4960
擴(kuò)展資料【豎式計(jì)算-計(jì)算結(jié)果】:先將兩乘數(shù)末位對(duì)齊,然后分別使用第二拍游賀個(gè)乘數(shù),由末位起對(duì)每一位數(shù)依次乘上一個(gè)乘數(shù),最后將所計(jì)算結(jié)果累加即為乘積,如果襲派乘數(shù)為小數(shù)可先將其擴(kuò)大相應(yīng)的倍數(shù),最后乘積在縮小相應(yīng)的倍數(shù)；
解題過程:
步驟一:2×80=160
步驟二:6×80=4800
根據(jù)以上計(jì)算結(jié)果相加為4960
