F.1 english math

(5+3)*8
=8*8
=64

5+3*8
=5+24
=29

第一個要先計括號。
第2個則是先乘除後加減。
努力吧~你遲D只會覺得呢D根本無難度~

calculate the results of (5+3)*8 and 5+3*8 separately.

separately係解分別地

請緊記要明白題目先好作答，以免犯下這種錯誤^_^

(5 + 3)*8
= 8*8 (calculate the operation within brackets first)
= 8x8
=64

5 + 3*8
= 5 + 24 (starting from left, calculate all division and multiplication first, then calculate additions and subtractions as you come to them)
= 29

Answer:(5+3)*8 - 5+3*8

=35
