That is perfectly fine but it can only be added if the variable is the same.It is also wrong as when you write "ab" it means a X b while you do not times a and b in this question but add them. So she is wrong<br /><br />In 2s + 4t its is the same case as the 2 variables are different so you cannot add them this jane is wrong again.Ian Harijantohttps://www.blogger.com/profile/14226016232595154134noreply@blogger.com
