RELATED ALGEBRA TOPICS  :   Order of Operations,  Forming algebraic expressions and translating phrases Let us learn how to express the numbers The mass of earth is 5,970,000,000,000,000,000,000,000 kg. Such large numbers are represented using exponents. We represent it as 5.97 x 1024 Thus 10 is base here and 24 is the power in 5.97 x 1024 Lets us see how to represent it. Look into the number. Place a decimal point at the end of the number. Now move the decimal 24 places to the left, such that you place the decimal point imediately after the first digit of the given number. What does this expression 5.97 x 1024 mean? 5.97 x 1000000000000000000000000 (24 zeros) OR 5.97 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10. Eg. Negative Integer The size of a atom is 0.0000000008 m. We represent it as 8 x 10-10 m. Here you need to move the decimal point10 places right. What does the expression 8 x 10-10 mean? 8 x 0.0000000001 OR 8 x 0.1 x 0.1 x 0.1 x 0.1 x 0.1 x 0.1 x 0.1 x 0.1 x 0.1 x 0.1 As the exponent decreases by 1, the value becomes one- tenth of the previous value. Generally mathematicians, scientists and engineers deal with very large and very small numbers on daily basis. They also do exponent addition, subtraction, multiplication, and division. Here is an example for each operation. When you add two or more exponents, the powers should be made equal first. Its is always better to convert the smaller power to the highest power. Just like addition, when you subtract exponents, the powers should be the same. When you multiply two exponents, just add the powers. am x an = am+n, where m and n are natural numbers. When you divide two exponents, subtract the powers. am/ an = am-n, where m and n are natural numbers. Scientific Notation worksheets free download pdf In addition, students work on multiplying and dividing numbers in scientific notation. These problems require applying exponent rules, which helps reinforce their algebraic thinking. As students solve more complex expressions, they build both accuracy and speed. Many worksheets also include real-world scenarios, such as scientific data or distances in space. These examples show students how scientific notation is used outside the classroom, enhancing relevance and engagement. In conclusion, these worksheets for grades 7 to 9 offer essential practice for building this critical math skill. With consistent use, students become comfortable with scientific notation and better prepared for high school science and math.

Home Algebra Order of Operations Order of Operations Worksheets Order of operations worksheets for grades 5 to 7 help students master solving expressions using the correct mathematical sequence, commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). These worksheets break down each step, making it easier for students to solve complex expressions accurately and confidently. These Order of Operations worksheets are the best for children who need to solve  mathematical expressions which involves more than one fundamental arithmetic operation. You can also call it PEDMAS worksheets. Thus order of operations are just a set of rules that tell you the order in which  math operation (Addition/ Subtraction/ Multiplication/ Division) should be done. Let us learn to solve arithmetic expressions Let us consider the expression 10- 2 x 3. If we subtract first 10 – 2 x 3 = 8 x 3 = 24 If we multiply first 10- 2 x 3 = 10- 6 = 4 We are getting two different answers. Hence, to avoid confusions and always arrive the correct answer, we follow a definite order to evaluate an expression. The rules to follow when you evaluate an arithmetic expression. 1. Do operations in Parentheses first 2. Exponents 3. Multiplication/ Division (Go from left to right, do whichever operation comes first) 4. Addition/ Subtraction (Go from left to right, do whichever operation comes first) Parentheses→Exponents→Division→Multiplication→Addition→Subtraction. Form an acronym, PEDMAS rule of Operations.
