The basic operations (**addition and subtraction**) are used in different forms such as multiplication (repeated addition) and division (repeated subtraction). Using these operations, the word problems are modeled into math expressions.

…how to perform the four arithmetic operations of **addition, subtraction, multiplication, and division**.

It is very important that students see mathematics, and the calculations they perform, as part of their daily life. Providing opportunities to apply basic concepts and operations in daily activities will **reinforce students' skills and motivate them to progress in mathematics**.

Operator – The symbol indicating a math operation is **an operator**, for example: + for addition. − for subtraction. × for multiplication.

NOTE: Even though **Multiplication comes before Division** in PEMDAS, the two are done in the same step, from left to right. Addition and Subtraction are also done in the same step.

The order of operations is as follows: 1) **simplify terms inside parentheses or brackets, 2) simplify exponents and roots, 3) perform multiplication and division, 4) perform addition and subtraction**. Multiplication and division are given equal priority, as are addition and subtraction.

As stated above, a graph in C++ is a non-linear data structure defined as a collection of vertices and edges.**Basic Operations For Graphs**

- Add a vertex: Adds vertex to the graph.
- Add an edge: Adds an edge between the two vertices of a graph.
- Display the graph vertices: Display the vertices of a graph.

The order of operations is as follows: **1) simplify terms inside parentheses or brackets, 2) simplify exponents and roots, 3) perform multiplication and division, 4) perform addition and subtraction**. Multiplication and division are given equal priority, as are addition and subtraction.

**Have significant difficulty learning basic math functions like addition and subtraction, times tables and more**. Be unable to grasp the concepts behind word problems and other non-numerical math calculations. Have difficulty estimating how long it will take to complete a task.

Addition, denoted by the symbol. , is the most basic operation of arithmetic. In its simple form, addition **combines two numbers, the addends or terms, into a single number, the sum of the numbers** (such as 2 + 2 = 4 or 3 + 5 = 8).

It means **if the addition of two numbers gives the third number, then subtraction of an added number from the third number will result in the original number**. Example: 4 + 7 = 11. Now, if we subtract 7 from 11, we get; 11 – 7 = 4.

Order of operations tells you to perform **multiplication and division first**, working from left to right, before doing addition and subtraction.

**A blank number line was originally proposed as a visual model or diagram for solving addition and subtraction operations**. An empty or blank number line is a visual diagram of a number line with no numbers or markers and is essentially used for solving word problems.

The five basic operations that a computer performs are **input, storage, processing, output and control**.

**We have great whole class math games to enjoy:**

- Addition and Subtraction Bingo. To play this game, create bingo cards with the answers to simple addition and/or subtraction problems.
- 101 Points.
- Action Addition and Subtraction.
- Math Twister.
- Shape Scavenger Hunt.
- Guess My Number.
- Multiplication and Division Bingo.
- Sign My Sheet.

Students **extend understanding of base-ten notation, fluency with addition and subtraction, standard units of measure, and describing and analyzing shapes**.

We can remember the order using PEMDAS: **Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)**. Created by Sal Khan.

Even though calculators can do the basic operations instantly, students should not use it all the time. When a student is always dependent on a calculator for solving problems of addition, subtraction, multiplication and division, **it may make them incapable of solving these basic operations manually**.
