2.    Find the product [ Kemudian darab]

3.    Lastly subtract [ Akhir sekali tolak ]

4.    Answer = 36

COMBINED OPERATIONS OF INTEGERS

Always follow the rule

Example 1 :

Question (a) Involve addition and subtraction operations, so the solution is from left to right

Step 1 : Find the answer for -5 - 8 that is -13

Step 2 : Then -13 + 4 so the answer is -9

Question (b) Involve division and multiplication, so the solution is from left to right

Step 1 : Find the answer for division the answer is -6

Step 2 : Then -6 multiply -5, answer is 30

Example 2

Question (a) Involving subtraction and multiplication, the solution is BODMAS

Step 1 : Find the answer for multiplication , 3 x (-7) = -21, but make sure you write at the back just like the position in question

Step 2 : Simplify the -(-) = +

Step 3 : Lastly, calculate the addition of -15 and 21, the answer is 6

Question (b) Involving addition, division and bracket, so use BODMAS

Step 1 : First, find the answer inside bracket [2 x (-8)]= -16

Step 2 : Followed by division, (-16)/(-16) = 1

Step 3 : Lastly addition , 12 + 1 = 13

Example 3

Question (a) Involving multiplication and division but in fraction
Step 1 : Simplify until get the smallest number
Step 2 : Multiply  6 x 1 = 6
Step 3 : Lastly, 6 divide with (-1), 6/(-1) = -6


Question(b) Involving division, addition and multiplication, use BODMAS
Step 1 : Find the answer for division and multiplication, but make sure you write the position same as in the question
Step 2 : Simplify the symbol +(-) = -
Step 3: Lastly - 4 - 14 = - 18
