Answer:
The answers are as shown in the explanation
Step-by-step explanation:
it should be noted that multiplication and division has a higher precedence than addition and subtraction. however, if there is parenthesis, then it will be given a preference before multiplication and division as such the order is as follows;
Parenthesis ()
percentage %
division /
multiplication *
Addition + and Subtraction -
a) for a - b - c - d
evaluation begins from left to right in the order 1 2 3
b) a - b + c + d
evaluation begins from left to right in the order 1 2 3
c) a / b * c * d
evaluation start from the left side since / is given precedence before the multiplication * in the order 1 2 3
d) a % b / c * d
here evaluation start from the % operator as it is given precedence before / and multiplication in the order 1 2 3
e) a % b % c % d
here evaluation start from the left side for the operator % in the order 1 2 3
f) a - (b - c) - d
the evaluation start from the bracket as it is given precedence before the subtraction operator in the order 2 1 3
g) (a - (b - c)) - d
similarly, evaluation start from the bracket as the precedence is before subtraction in the order 2 1 3
h) a - ((b - c) - d)
here, evaluation process start from the bracket operator as it has a high precedence before subtraction in the order 3 1 2
i) a % (b % c) * d * e
here, evaluation start from the bracket, then the % operator before the multiplication, in the order 2 1 3 4
j) a (b - c) * d - e
evaluation start from the bracket, then the multiplication operator before the subtraction, in the order 3 1 2 4
k) (a+ b) * c +d * e
evaluation start from the bracket operator, then the multiplication and then addition in the order 1 2 4 3
l) (a+ b) * (c / d) % e
here, evaluation start from the bracket, then the % operator, then division and multiplication in the order 1 4 3 2
