=My task = To explain algebraic expressions, Simplifying algebraic expressions using multiplication and division and simplifying algebraic expressions using addition and multiplacation.

An algebraic expression is when you replace any number with a letter for example you could work out how much money can be shared around by replacing the number of people with p making the equation $100 divided by p. Another thing you could find out is how many hours you have worked by replacing the number of hours working with h and the earnings $40 and the equation is now 40xh. P.S the letter used can be any letter but it is better if it related to the topic.
 * Algebraic Expressions **

 **simplifying algebraic expressions using addition and subtraction ** Adding algebraic expressions is just like adding normal numbers heres an example 2y+6y=8y but if you were to have more than two different letters it would be like this, 2x+4y+3x= 5x+4y this works by adding 2x and 3x which equals 5x which becomes 5x+4y, you just have to remember that the letters have to be alphebetical order. Subtracting works in the same way here`s an example 6m-3m=3m. you can also mix them together for example 2m+5m+6n-n=7m+5n. P.S if a letter is alone like in the last example it is then called 1.

 Using multiplication is a little more complicated, lets start with a simple example 2xm=2m to answer this you just remove the multiplication sign and put the numeral and the letter are together. Now lets try a harder one 4x2xmxn=8mn for this one you just times 4 by 2 which equals 8 and then just add the m and the n to the 8 in alphabetical order making the answer 8mn. division is probably the hardest one, but when dividing you just divide the letter and the number for example n/3= n over 3 or mx4/2=4m over 2.  P.S (/) is equivalent to divide
