Math tricks 1: Dividing by grouping 345÷15 =(300÷15)+(45÷15) =20+3 =23 In example here,separate dividend into two groups:(300÷15)+(45÷15),and add up the answer. Math tricks 2: Dividing by augmenting Example: 418÷11 =(440÷11)(22÷11) =402 =38 In example here,418 was augmented to 440,that is 418=44022
Math tricks 3: Dividing by break apart the divisor 325÷25 =325÷(5×5) =325÷5÷5 =65÷5 =13 In example here,break 25 to 5 and 5(25=5×5).
