Addition and subtraction are examples of arithmetic operations, specifically binary operations. These operations involve combining two numbers to produce a single result. In mathematics, addition is considered an operation that combines two numbers to find their sum, while subtraction is an operation that finds the difference between two numbers. Both addition and subtraction are fundamental operations in arithmetic and are used extensively in various mathematical applications.
What else can I help you with?
When given an algebraic expression involving subtraction why is it best to rewrite the expression using addition before Identifying the terms?
Rewriting an algebraic expression involving subtraction as addition simplifies the process of identifying and combining like terms. This approach adheres to the mathematical principle that subtraction can be expressed as the addition of a negative, making it easier to manage the signs of the terms involved. Additionally, it helps maintain clarity and reduces the risk of errors during simplification. Overall, this method streamlines the manipulation of the expression.
How can one learn subtraction?
There are a number of ways one can learn subtraction. Perhaps the best way is to find one that can spend some time teaching one subtraction. There are a number of workbooks also available.
Which operations don't require a common denominator?
Addition and subtraction are the only fraction operations that need a common denominator. Multiplication, division, and exponents do not need a common denominator. In fact, it is best to use reduced fractions otherwise it gets very messy.
What is the order of operations when simplifying?
It is best remembered by its acronym - BIDMAS (UK) or PEMDAS (US). B = Brackets (P = Parentheses) I = Index )E = Exponent) DM (MD) = Division and Multiplication, with equal priority, left to right. AS = Addition and Subtraction, with equal priority, left to right.
Which best describe how to evaluate a variable expression?
To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.

In math what is a fact family?
A fact family is when the same 3 numbers are used in addition and subtraction sentences. An example would be 3+4=7, 4+3=7, 7-4=3 and 7-3=4
What is the best calculator for a elementary student?
Any calculator having sturdy design , 10 digit large display and basic functions like addition, subtraction, multiplication, division, percentage and square root is good enough for elementary students.
What number best completes the sequence 7 1 5 - 3 7?
The sequence appears to be alternating between addition and subtraction operations. Starting with 7, we subtract 6 to get 1, then add 4 to get 5, subtract 8 to get -3, and then add 10 to get 7. Following this pattern, the next operation would be subtraction, so we subtract 12 from 7 to get -5. Therefore, the number that best completes the sequence is -5.
