加減乘除數

發問:

1. 係咪計除數先，跟住4捨5入 6.9減333除694.82 = 4.8 = 6.9減4.8 = 2.1 === 209除48減4.14.35 = 4.4 = 4.4減4.1 = 0.3 === 21加4540除23119.65 = 19.7 = 21加19.7 = 40.7 ====2. 乘除係咪不分先後，又係4捨5入 321乘21除23 = 6741除23293.08 = 293.1 = 292.95... 顯示更多 1. 係咪計除數先，跟住4捨5入 6.9減333除694.82 = 4.8 = 6.9減4.8 = 2.1 === 209除48減4.14.35 = 4.4 = 4.4減4.1 = 0.3 === 21加4540除23119.65 = 19.7 = 21加19.7 = 40.7 ==== 2. 乘除係咪不分先後，又係4捨5入 321乘21除23 = 6741除23293.08 = 293.1 = 292.95 乘23292.95 = 293 = 293.1 ===== 計埋直式，唔該

最佳解答:

計乘除先，跟住4捨5入，跟住加減 6.9-333/69 4.8260869...=4.8 =6.9-4.8 =2.1 ____________________________________________________________________ 209/48-4.14.35 = 4.4 = 4.4-4.1 = 0.3 ____________________________________________________________________ 21+4540/23119.65 = 19.7 = 21+19.7 = 40.7 ____________________________________________________________________ 乘除不分先後，跟住4捨5入 321x21/23 = 6741/23293.08 = 293.1 = 293.1 ------------------------------------------------------------------------------------------------------------ 2009-02-16 16:13:59 補充： 不計直式,因為難寫
