number sequence vs number sentence
In the material I'm studying, it says the following;
1. A number sequence is when addition is written horizontally.
2. A number sentence is when subtraction and multiplication are written horizontally.

Is this really specific to addition, subtraction and multiplication, or can they all be interchanged?

Could I say that, 2 + 4 = 6 is a number sentence and that 4 x 5 = 20 is a number sequence?

Hello, MrDiedel!

What is the source of this mathematical rubbish?
Are you omitting some clarification?

Statement 1 makes no sense.

A number sequence is an ordered list of numbers.
Example: 2, 5, 8, 11, 14, ...
. . which may or may not have a pattern.

We see that: . $2 + 4$ is not a number sequence . . . and neither is: $\begin{array}{c}\;\;\;2 \\ +\,4 \\ \hline \end{array}$
Who cares if it is written horizontally or vertically?

Statement 2 might make sense if we knew what a "number sentence" is.
Perhaps it is an English sentence containing a number?
Example: "There are twelve objects in a dozen."

I seriously recommend you discard that material immediately.
It is chillingly irrational and dangerously wrong.

The statement...
Addition problems are sometimes written in a horizontal form such as: 6 + 5 = 11.
This form is also known as a number sentence. It is read as, "Two plus three equals five." In a manner of speaking, this number sentence shows that 2 + 3 can be more simply expressed as 5.

The statement....
Subtraction problems are sometimes written in a horizontal form such as:

5 – 3 = 2

This form is also known as a number sentence. It is read as, "Five minus three equals two."

The statement....
Multiplication problems are sometimes written in a horizontal form such as:

3 x 5 = 15

This form is called a number sentence. It is read as, "Three times five equals fifteen."

So, where did you see "number sequence"?

HA HA HA! Dang, that really makes a guy feel embarrassed! I'm sorry to have bothered everyone. Apparently I've misread the materials. (NO, it's a conspiracy and they've changed it back just so I'll go crazy!) Thanks for replying. I'll try to read more carefully next time. Have a great day.

Question:
So, 2+4=6 can be called a number sentence?
As well as any subtraction, multiplication and division?

Re: number sequence vs number sentence
Interesting, Wikipedia has an article on "number sentences."
Number sentence - Wikipedia, the free encyclopedia

By that definition, 5+4 = 9, 6*3 = 18, and 5-3 = 2 are considered number sentences.

A sequence is an ordered list of numbers or objects such as: 1,2,4,8,16,..., or cat,dog,chicken,horse.

Thank you. I feel Wikipedia's information is usually trustworthy. The information in that link is quite simple and clear. Too bad my eyes lied to my brain in the first place. Or perhaps my brain didn't trust my eyes? ha ha
