# Writing basic expressions with variables

Sal writes an expression to represent 11 more than a.

• What do you put when it says "what is the quotient of 9 and c?"
• Quotient means division. This is asking you for the division of 9 and c. Does that help?
• ok so i got a question, 8 increased by g. Simple right? Just supposed to write that in an expression. Same as you would say m decreased by 2 is m-2. But what is 8 increased by g? Just simple adding 8+g?
• Yes. 8 + g. Everything you can do with a number (add, subtract, multiply, divide, exponentiate, etc.) you can do with a variable. It's just a number with a different name.
• what does increased by mean? Is it multipilying or what?
• It means addition
If you have 3 apples and I give you 2 more, then your number of apples has increased by 2.
3 + 2 = 5
You now have 5 apples.
Hope this helps.
• At and at , for those questions I write the answers as :7(r) and 10(u).
Is that right because that's how I learned it in school.

• 7(r) and 10(u) do mean "7 times r" and "10 times u", so they do answer the question correctly.
However, in mathematics, we usually want to write things as simply as possible, especially when parentheses are involved. That's why 7r and 10u are preferable answers.
• how is this so post to help me with Algerbraic Expressions??
• so...actually using variables and stuff can help in future problems of algebra like finding the whole sum of variable and things
• is it possible to put the variables before the number in the equation when using multiplication.
• When using multiplication, it is possible.
You can write `5x` as `x5` because the commutative property of multiplication tells us that these are the same / equal. But, it is generally not written that way. It is much easier to read with the numbers in front of the variable.
• Write an expression for "the product of 11 and w."What about this one ?
