5 times 5 plus 5 times 5 minus 5 divided by 5
An expression which combines numbers and operations
Here is the correct defenition: Algebraic Expression is an expression which is obtained by performing a finite number of the following operations on symbols representing numbers: addition, subtraction, multiplication, division, raising to a power.
evaluate.
A number sentence that equals or that has an equal sign.
That word "equals" in there makes it an equation.
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
an algebraic expression is an expression built up from constants, variables, and a finite number of algebraic operations (addition, subtraction, multiplication,division and exponentiation to a power that is a rational number). For example,
It is called evaluating the equation.
An expression can be that, but it can also be a combination of such terms and other mathematical operations. For example, 3a + 27b^2/sin(27c) provided c is not 0.
An equation states that an expression is equal to either a number or another expression.The 'equals' sign ( = ) is the tip-off that you have an equation.
"Atomic number" is a characteristic of a chemical element and equals the number of protons in each nucleus of an atom of the element.
A mathematical operation is a process such as addition, subtraction, multiplication or division. The word can also include the use of brackets or parentheses, squaring a number, integrating, differentiating, and so on. Basically, this covers any process that changes the value or state of the number or expression on which it is operating.
