Multiplication of Algebraic expression:
please give me introduction about this
Answers
Answer:
If there are no brackets in an algebraic expression, it means that multiplication and division must be done first, and addition and subtraction afterwards. For example, if x=5 the expression 12+3x means "multiply 5 by 3, then add 12". It does not mean "add 12 and 3, then multiply by 5".

A Puzzle
What is the missing number?
× 4 = 8
The answer is 2, right? Because 2 × 4 = 8.
Well, in Algebra we don't use blank boxes, we use a letter. So we might write:
x × 4 = 8
But the "x" looks like the "×" ... that can be very confusing ... so in Algebra we don't use the multiply symbol (×) between numbers and letters:
We put the number next to the letter to mean multiply:
4x = 8
In English we say "four x equals eight", meaning that 4 x's make 8.
And the answer is written:
x = 2
How to Solve
Instead of saying "obviously x=2", use this neat step-by-step approach:
Work out what to remove to get "x = ..."
Remove it by doing the opposite
Do that to both sides
And what is the opposite of multiplying? Dividing!
Have a look at this example:
