An expression is a sentence with a minimum of two numbers and at least one math operation. This math operation can be addition, subtraction, multiplication, and division. The structure of an expression is:

Expression = (Number, Math Operator, Number)

For example,

= 7 + 9

= 23 × 4

= 37 – 6

= 25 + 9 – 4 ÷ 2

In all the given expressions, a math operator is used between the two numbers.

A math expression is different from a math equation. An equation will always use an equivalent (=) operator between two math expressions.

For example,

= 25 + 7 = 64 ÷ 2

= 20 × 5 = 102

The structure of defining math expression advances in different grades. In early grades, children are expected to write math expressions using numbers and operators. Later on, words help students to form a math expression.

Let’s consider a word problem.

Tom has to fill a box with oranges and apples. The number of apples should be 5 more than oranges. Tom picks 3 oranges each time and repeats it 5 times. Count the total number of oranges and apples.

To solve this, formulate the math expressions as follows:

= Number of oranges = 3 × 5

= Number of oranges = 15

Number of apples = Number of oranges + 5

= Number of apples = 15 + 5

= Number of apples = 20

Total number of fruits = Number of oranges + Number of apples

Third math expression will be:

= 15 + 20

= 35

Answer from: Quest

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

$m\angle qrt=156^o$

$m\angle qst=156^o$

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
