Pre AlgebraPre algebra is the subject you need to understand before moving on to learn algebra. In other terms, you can say that pre algebra is the perfect platform from where you can move on to algebra. However, we will talk about pre algebra as a separate entity here. Let us have a look at the key topics of pre algebra you must know: Negative numbers Learn basic facts of adding, subtracting or multiplying negative numbers. For example, always remember:
Adding odd and even numbers Here, just remember:
Decimal numbers While adding or subtracting decimal numbers, always place the numbers so that the decimal points are vertically aligned. For example, 6.231 + 0.044 = 6.275. While multiplying decimal numbers, multiply like you multiply whole numbers. Then add the decimal places in both numbers to find the position of the decimal point in the product. While dividing, move the decimal point in the divisor to the right as necessary to make the divisor a whole number. Then the decimal point in the dividend is moved to the right the same number of places. The decimal point in the answer is placed just above the decimal point in the dividend. These facts are vital in pre algebra. Square Root To learn square roots, remember the following formulas:
Reducing to lowest factors Divide the top and the bottom by the same prime numbers until no more common prime number can be found. e.g, 24/36 =4/6=2/3 Converting mixed number to improper fraction In this, remember the following formula: Converting improper fraction to mixed number Divide the denominator into the numerator. The whole part of the answer is the whole part of the mixed number. The remainder will be the numerator of the fraction of the mixed number. Finally, just learn these topics and practice them as much as possible. With time you will surely master pre algebra, which will lay a good foundation for your algebra classes.
