It means multply
e.g. 5a means '5' multiplied to the value of 'a'.
As in all multplied/addition.
3+3+3+3+3 = 5 X 3 = 15
Instead of writing all the plusses , we shorten it to multiply.
Similarly
a + a +a + a + a = 5 X a = 5a
In algebra the multiplication sign (x) is never shown as it may be confused with the unknown 'x'.
In algebra
addition is shown as 'a + b
subtraction is shown as 'a - b' .
multiplication is shown as 'ab'
division is shown as 'a/b' ( like an fraction).
it means to multiply the number by the letter for example:
4A+2
it means 4 times A. above your problem it may or may not say what "A" is, if it does you will need to multiply 4 by that number. if it does not show what A is you will have to find out what A is, for example:
"4A=8"
so to find A you need to find what times 4 is 8 which is 2.

What does the line over a letter in algebra means?
It can mean that it is a vector.
What does is mean in algebra?
In Algebra, "is" means Equal (=).
What does it mean with the signs in algebra?
well the . is multiplication. a number and another number separated with a _ is multiplication. a + is addition, and a - is subtraction. got it? teehee!
What does i mean in algebra?
i means imaginary number or what you would find the square root of to make -1
What does a number and two letters mean in algebra?
Generally speaking, a letter in algebra refers to a variable, that is, it is a placeholder for any specific value that can be used in that equation.In algebra syntax, a number next to a variable, or a variable next to another variable, with no explicit arithmetic symbol between them, mean to multiply the two values.So:2aMeans to multiply the variable value of "a" by two.In your question:2aball values should be multiplied. So, the result would be 2 times the variable value of "a" times the variable value of "b".
What does the letter x mean in algebra?
An unknown number
What does the letter n mean in algebra?
"n" stands for an unknown number.
What does b mean in math?
"b" is simply a letter in algebra to replace an unknown number.
How do you algebra?
In algebra, there will be letters. Each letter represents a number. Different letters stand for different numbers. e.g. x=1 but y=3. if there are many X's, they all mean the same thing.If there is a number before the letter, you multiply the number by what the letter represents. So 3p means 3*p. This is very simple algebra. I haven't learned complex algebra yet, but i can understand it. But can't explain it well.
What does n mean in algebra?
n is any number, (it is not n because it is the first letter of the word number,because the 'n' could be a 'q' or a 'h') Basically, 'n' is any number, and usually when working with algebra, it is easiest to work backwards
What does the variable mean in algebra?

What does algebra letters mean?
a variable (an unknown number/ any number).
What does the line over a letter in algebra means?
It can mean that it is a vector.
What is a letter that is used in place of a numeral mean?
if there is a letter (example n, z ) instead of a number in algebra it stands in place of that number. this means if you are doing multiplication you are going to divide the numbers to get the answer for your letter . if you are doing division you do it the other way around! easy
What does the letter A mean in algebra?
