Maths Brackets

This year in maths we have done 5 different subjects to learn. We have done coordinates, basic algebra ,brackets, factorising and linear algebra. I have chosen to explain brackets with brackets you have a number outside the brackets and 2 or more numbers or letters if you are doing algebra. Whatever is inside the brackets has to be multiplied by whatever is outside the bracket. Here's an example 3(4+5) 3x4=12 3x5=15 the answer is 12+15. if its a letter outside the brackets it turns into algebra. It would be the letter and the number added to make the equation here's an example x(4+5)= 4x+5x. If its a letter inside and outside the bracket it would be x² or x³ etc depending on how many x's are in the bracket. Here is my work on brackets that about covers brackets.
