Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

Answer to Problem 35HP

The required expression is (64−20)÷4+6

Explanation of Solution

Given:

The expression is (64−20)÷4+6

Calculation:

Let first consider the expression,

  (64−20)÷4+6

Now, let us place a parenthesis as shown below

  (64−20)÷4+6

Now, evaluate this expression by following the order of operations,

First solve brackets, then multiply or divide in order from left to right and after that addition or subtraction in order from left to right.

  (64−20)÷4+6=44÷4+6=11+6=17

Thus the required expression is

  (64−20)÷4+6

Conclusion:

Therefore, the required expression is (64−20)÷4+6

(b)

To determine

To place:different parentheses to get the value other than 17 and evaluate

Answer to Problem 35HP

The required expression is (64−20)÷4+6

Explanation of Solution

Given:

The expression is (64−20)÷4+6

Calculation:

Now, for second part consider the expression

  (64−20)÷4+6

Now, evaluate this expression by following the order of operations,

First solve brackets, then multiply or divide in order from left to right and after that addition or subtraction in order from left to right.

  64−(20÷4)+6=64−5+6

Now, since on going from left to right first operation is subtraction.

Subtract first and then add.

  64−(20÷4)+6=64−5+6=59+6=65

Thus the required expression with answer other than 17 is

  64−(20÷4)+6

Conclusion:

Therefore, the required expression with answer other than 17 is 64−(20÷4)+6
