Practice math facts online – Introduction:
In algebra basic arithmetic operation (addition, subtraction, multiplication, and division) generally used in day to day life. Addition defined as adding the two numbers. Subtraction (-) defined as the inverse of addition. Multiplication defined as the product of numbers. Division can be considered as repeated subtraction.
In online, students can learn about math facts. Through online, students can have interactive sessions with tutors. Online is one of the efficient tools for one to one learning. In these articles we are going to see about practice math facts online. Understanding What is a Line Segment is always challenging for me but thanks to all math help websites to help me out.
Practice Math Facts Online – Addition and Subtraction Rules and Examples:
Practice math facts online - Addition rule with examples:
Positive + Positive = Positive: 7 + 7 = 14
Negative + Negative = Negative: (- 5) + (- 6) = - 11
Addition of a negative and a positive integer: Use the sign of the larger number and subtract, examples are,
(- 5) + 4 = -1
7 + (-2) = 5
Practice problems:
1. (-9) + 2 =?
Answer: (-7)
2. 5 + (-1) =?
Answer: 4
Practice math facts online - Subtracting rule with examples:
Negative - Positive = Negative: (- 4) - 2 = -4 + (-2) = -6
Positive - Negative = Positive + Positive = Positive: 4 - (-4) = 4 + 4 = 8
Negative - Negative = Negative + Positive = Use the sign of the larger number and subtract (Change double negatives to a non negative)
(-5) - (-2) = (-5) + 2 = -3
(-2) - (-4) = (-2) + 4 = 2
Practice problems:
1 (-9) – 2 =?
Answer: (-11)
2. 5 - (-1) =?
Answer: 6

Practice Math Facts Online – Multiplication and Division Examples:
Practice math facts online - Multiplication rules:
Rule1: Multiplication of two integers by the related signs resolve be positive sign
a) Positive x positive = positive
b) Negative x negative = positive
Rule2: Multiplication of two integers by the unlike signs will be negative
a) Positive x negative = negative
b) Negative x positive = negative
Example problems:
1. Positive x positive = positive
Example: 2 * 4 = 8
2. Negative x negative = positive
Example: (-2) * (-6) = (12)
3. Positive x negative = negative
Example: 6 * (-3) = (-18)
4. Negative x positive = negative
Example: (-4) * 3 = (-12)
Practice problems:
1. (-7) * 2 =?
Answer: (-14)
2. (-5) * (-2) =?
Answer: 10
Practice math facts online - Division rules and example problems:
Rule 1: Division of two integers by the related signs resolve be positive sign
a) Positive ÷ positive = positive
b) Negative ÷ negative = positive
Rule 2: Division of two integers by the unlike signs will be negative
a) Positive ÷ negative = negative
b) Negative ÷ positive = negative
Example problems:
1. Positive ÷ positive = positive
Example: 9 ÷ 3 = 3
2. Negative ÷ negative = positive
Example: (-14 ÷ (-2 = 7
3. Positive ÷ negative = negative
Example: 10 ÷ (-2) = (-5)
4. Negative ÷ positive = negative
Example: (-15) ÷ (3) = (-5)
Practice problems:
1. (-9) ÷ 3 =?
Answer: (-3)
2. 25 ÷ (-5) =?
Answer: (-5)
