    Using Distributive property you can do it.. Multiplication by minus sign here means multiplication by -1./.. so according to distributive property a*(x+y)=a*x+a*y also -1*-1 = 1 -1 * 1 = -1 1*1 = 1 ie -ve multiplied by -ve = +ve +ve multiplied by -ve = -ve -ve multiplied by +ve = -ve +ve multiplied by +ve = +ve hope now you can do it now by yourself

    that is a*b = c means a is multiplied by b and the answer is c

    on multiplying -ve with -ve, u get +ve. -ve*+ve gives _ve.

    ok..Let us start from the beginning... expand bracket means multiplying the terms outside the bracket with the terms inside.. that is for example 1.expand bracket a*(x+y) means multiply 'a' with the terms inside the bracket You understand that??

Here if we want to find the term inside bracket of blow question s*(t) inside the bracket term means the term inside the symbols ( ) here the term is side the symbol is 't' the term outside the bracket means the term outside the symbol ( ) here the term outside that symbol is s... understood?

    ok... 2*(5+3) this means we have to multiply the term outside the bracket (here 2) with terms inside the bracket (5+3) what this means is that we have to multiply 5 by 2 and 3 by 2 and have to add the result that is 2*(5+3) = 2*5 +2*3 = 10 + 6 = 16 you got this

    2*2=4 and 2*6=12 so 4+12
