Addition:
1. look for like terms, combine like terms by adding their numerical coefficient. In adding the numerical coefficient, you have to consider the rules in adding integers.
a. to add two numbers having like signs, add their absolute values and prefix their common sign, then bring down the literal coefficient.
b. to add two numbers having unlike signs, find the difference of their absolute values and prefix to the difference sign of the number having a greater absolute value, then bring down the literal coefficient.
Subtraction:
1. multiply the subtrahend by -1 and proceed to adding algebraic expression.

What is a mathematical phrase that contains operations numbers or variables?
A mathematical phrase that contains operations, numbers, or variables is called an algebraic expression. Algebraic expressions consist of constants (numbers), variables (letters representing unknown quantities), and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. These expressions can be simplified, evaluated, or manipulated using algebraic rules and properties.
What are the rules when solving a problem with many different operations?
PEMDAS. Parenthases, exponent, multiplication, division, addition, subtraction. Do parenthases first then exponents. Multiplication and divison are left to right. Then it's addition and subtraction, left to right. Hope I helped!
When simplifying an expression you perform which operations inside grouping symbols first?
Within parentheses or similar symbols, the same rules apply as when you don't have parentheses. For example, multiplication and division have a higher priority (or precedence) than addition and subtraction.Within parentheses or similar symbols, the same rules apply as when you don't have parentheses.

What are rules telling in what order to do operations?
"PEMDAS" P- Parentheses E- Exponents M- Multiplication D- Division A- Addition S- Subtraction Note: multiplication and division are interchangeable. addition and subtraction are also interchangeable. parentheses THEN must stay the same, though.
In brackets rules on addition and multiplication which first?
Remember the golden rule: BIMDAS. If you haven't heard it before B means bracket, I means indices, M means multiplication, D is division, A is Addition and S is subtraction. So to answer your question multiplication comes before addition.
