In this chapter, we will be learning about rational numbers.
Rational numbers include integers, which are positive and negative whole numbers. We will also learn about basic arithmetic operations involving integers, such as addition, subtraction, multiplication, and division.
Additionally, we will explore positive and negative fractions, which are numbers expressed as a ratio of two integers. We will also study positive and negative decimals, which are numbers expressed with a decimal point.
By the end of this chapter, we will have a good understanding of rational numbers and how to work with them in different forms.
• Identify positive numbers and negative numbers based on real situations
• Identify and describe integer
• Delegate integer on the number line and make an association between integer value with the integer position compared to other integer on the number line
• Comparing and arrange integers in order
• Adds and subtracts integers using a number line or other appropriate method. Next, generalize about adding and subtracting integers
• Multiply and divided integer using various methods. Next make generalization about multiplication and integer divisions
• Calculation involves the combination of the basic operations of the arithmetic for integer in accordance with the order of operations
• Elaborate on the laws of arithmetic operations namely Identity Law, Commutative Law, Associative Law and Distributive Law
• Make efficient calculations using basic arithmetic operations law
• Solve the problems involving integer
