What does a number followed by a letter in algebra mean?

Answer 1

Oh, dude, like when you see a number followed by a letter in algebra, it means you're dealing with a term where the number is multiplying the letter. It's like saying "hey, little letter, you gotta hang out with big number over here." So, if you have 3x, it's like saying 3 times x, which is just math's way of keeping things interesting.

Answer 2

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).

Answer 3

Well, isn't that just a happy little question! When you see a number followed by a letter in algebra, it usually means multiplication. The number is being multiplied by the letter. Just think of them as good friends working together to create a beautiful equation on your canvas of math.

Answer 4

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.
