An indice is a number that means how many times a number should be timed by itself eg. 73 this would be 7x7x7. What’re indices?
What are the rules around them -
They are so you don't have to write out a long equation eg 5 x 3 x 3 x 3 x 3 instead this would be 5 x 3^4. you are to always use BIDMAS (brackets, indices, division, multiplication, addition, and subtraction.) A - x - = + a + x + = + a - x + = - and a + x - = -
What happens to + and - numbers?
If it was 5 x -3^3 this would become a negative answer since the indices are an odd number. Indices would become a positive answer by eg 5 x -3^4 because the indices is an even number.
Nice job David, I really like the way that you have explained what an indice is and you have given a couple of examples as well as included some pictures. Maybe next you could space out where you were explaining about positive and negative numbers because seeing all the + and - got a little bit confuseing but the picture helped out a lot. Overall I think you did a great job keep the up the good work.
