英文學校之數學

有誰知道這一句是什麼意思?

You want to estimate 5.25-3.3.Why would using front-end estimation

and adjusting tell you more about the answer than rounding?

還有一句

Wesley estimated 5.82-4.21 to be about 2.Is this an overestimate or an

underestimate?Explain.

有人知道ㄇ?知道的話,拜託!因為這是我的功課!

P.S我還是個小學生!!

    You want to estimate 5.25-3.3.Why would using front-end estimation and adjusting tell you more about the answer than rounding?

    你想要估算 5.25-3.3。為什麼你使用前端估算和調整法比四捨五入法的答案還要多?

    Wesley estimated 5.82-4.21 to be about 2.Is this an overestimate or an

    underestimate?Explain.

    衛斯里估算5.82-4.21大約為2。這個答案是超估還是低估了?請解釋。

    PS:很好奇你念哪一個國小耶,怎麼數學用英文出題呢?

    不知道你們所學的前端估算(front-end estimate)是指什麼算法。

    5.23-3.3=1.95,前端估算5-3=2,比1.95多,

    因為前者小數點比後者小,是這個意思嗎?

    5.82-4.21=1.61,Wesley的答案2,算是超估(overestimate)吧...

    你想要估計 5.25-3.3 。為什麼將會使用前置器判斷

    而且調整超過圓化告訴你更多關於答案的事?

    衛斯理估計 5.82-4.21 是大約 2 。這是估計過高或一

    低估?解釋。
