What is an math's indices?

 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.
