<h2>Question</h2>
Simplify the following
A . ( 12 ) x ( − 16 ) + 16
b . ( − 34 ) ÷ ( − 23 ) + 14
c . ( − 45 ) ÷ ( − 15 ) + 13
d . ( 23 ) - ( − 16 ) - 13
e . ( − 42 ) + ( - 16 ) ÷ 13
<h2>Answer:</h2>(A) -176
(B)
(C) 16
(D) 26
(E)
(A)
( 12 ) x ( − 16 ) + 16
Following the rules of BODMAS
<em>=> Solve the brackets first</em>
12 x -16 + 16
<em>=> Next, solve the multiplication(x)</em>
-192 + 16
<em>=> Solve the addition and subtraction</em>
-176
(B)
( − 34 ) ÷ ( − 23 ) + 14
Following the rules of BODMAS
<em>=> Solve the brackets first</em>
-34 ÷ -23 + 14
<em>=> Next, solve the division(÷)</em>
+ 16
The negative signs can cancel out.
+ 16
<em>=> Solve the fraction</em>
+
(C)
( − 45 ) ÷ ( − 15 ) + 13
Following the rules of BODMAS
<em>=> Solve the brackets first</em>
-45 ÷ -15 + 13
<em>=> Next, solve the division(÷)</em>
+ 13
The negative signs can cancel out.
+ 13
3 + 13
<em>=> Solve the addition</em>
3 + 13 = 16
(D)
( 23 ) - ( − 16 ) - 13
Following the rules of BODMAS
<em>=> Solve the brackets first</em>
23 - -16 - 13
<em>=> Next, - - will give + </em>
23 + 16 - 13
<em>=> Next solve the addition</em>
39 - 13
<em>=> Next solve the subtraction</em>
39 -13 = 26
(E)
( − 42 ) + ( - 16 ) ÷ 13
Following the rules of BODMAS
<em>=> Solve the brackets first</em>
-42 + -16 ÷ 13
<em>=> Next, + - will give -</em>
-42 - 16 ÷ 13
<em>=> Next solve the division</em>
-42 - 16 ÷ 13
-42 -
<em>=> Next solve the fraction</em>
-
