其實主要係考一d普通既 加減乘除 運算,唔會話太難,又或乘數表....... 比如 加減乘除 運算:係supermarket買包$9朱古力, 你得一張$100應找翻幾多等 乘數表:可能要你心算 , e.g.6*4=? ,9*9=?等 只是學識 加減乘除 運算同乘數表都ok

positive number正數 negative number負數 number line數線 (5x-2y)+(7x-3y) =5X-2y+7x-3y =12x-5y (3x+4)-(6x-3) =3x+4-6x+3 =3x+7 好易, 好似約簡5x+7x=12x ;-2y-3y=5y 所以(5x-2y)+(7x-3y)=12x-5y
加 = plus/ add 減 = minus/ subtract(b is subtracted from a => a-b) 乘 = multiply/ times 除 = divide 畢氏定理= Pythagoras theorm 度數 = degree 未知數 = unknown 對頂角 = opposite angles 同位角 = corresonding angles 內錯角 = alternate angles 全等...
