Why is it important to have rules for simplifying an expression that contains more than one operation?
Because if you didn't, there could be more than answer and there would be no way to decide which is correct.
For example, "10+6/2": If you do this from left to right, you get 16/2 = 8. If you follow the rules, you do the division before the addition: 10+3 = 13.
13 is correct.
If you wanted 8, you would write (10+6)/2, then you would have to simplify inside the parentheses before dividing.

What is an mathematical phrase involving constants variables and operation symbols?
It is an expression and if it contains an equality sign then it is an equation.
What is a mathematical phrase that contains operation numbers and or variables?
A mathematical phrase that contains operation numbers and variables is called an "expression." For example, (3x + 5) is an expression where (3) and (5) are constants, (x) is a variable, and the operation is addition. Expressions can also include other operations like subtraction, multiplication, and division. Unlike equations, expressions do not contain an equality sign.
What contains varibles numbers and at least one operation?
An algebraic expression contains variable numbers and at least one operation. For example, the expression (3x + 5) includes the variable (x) and the operations of addition and multiplication. Such expressions can represent a wide range of mathematical relationships and can be simplified or solved for specific variable values.
What do you call an expression that contains only numbers and operations?
A expression that only contains numbers is a Numerical
What expression contains variables?
equations
What is an expression that contains a variable a number and at least one operation?
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
What is the solution of this problem in math- simplifying each expression- -8-10x-2?
The question contains an expression -10-10x = -10(1+x). Since it is not an equation nor inequality, it cannot have a solution.
