Question

If axb is ab so why 2x4 cannot be 24

Answer 1

ab is a short form of writing a*b.ab and a*b mean the same.as the value of a and b is not definite,it can be written as ab.whereas when 2 and 4 are written together with no symbol their values change completely.2*4 is 8 whereas when we write 2and4 together the value is 24.
