Algebra, an interesting branch of Mathematics is where we use English alphabet along with numbers. This advanced Math can describe many types of real- world phenomenas which you will be learning here. Skills to express Algebraic equations, evaluate expressions, solve one-step, two- step and multi- step equations, Inequalities, and many more are covered in this section.
Algebra is fun!!! You will get to know it here.
Ratio is used to compare two or more quantities of the same units thereby indicating how much of one quantity is present in the other quantity. There are two types of ratio – part to part ratio and part to whole ratio. Part to Part is between two quantities whereas Part to Whole is for a group. Ratio between two quantities say x and y is represented as x : y . This can be read as ‘x is to y‘.
Order of Operations, as the name suggests, is the order in which operations like addition, subtraction, multiplication and division need to be performed. Let us simply follow PEDMAS. PEDMAS is the acronym for Parentheses, Exponents, Division/ Multiplication, Addition/ Subtraction. Here are a number of worksheets to learn and perform arithmetic operations in order.
Scientific Notation is used to easily handle very large and very small numbers. It is much easy to express numbers in powers of 10 instead of writing or calculating large values as such. It is to be kept in mind that the shortened number is between 1 to 10 and then multplied in powers of 10. This form is generally used by scientists, engineers and mathematicians.
Algebraic expressions involves variables and constants. Using these variables, constants and arithmetic operations, a statement or a phrase can be translated into algebraic expression. Similarly, an expression be translated into a statement. These worksheets teach you to frame algebraic expressions and to translate phrases.
