There are several addition expressions that can equal the number 7, depending on how you combine different integers. For example, you can represent 7 as 7 itself (7), or as combinations of smaller integers like 3 + 4, 2 + 5, and 1 + 6. If you also consider the order of the addends, the total number of unique addition expressions increases. However, the exact count can vary based on whether you allow repeated numbers and the range of integers considered.

How can a subtraction problem be turned into a addition problem?
When you have a negative number after the subtraction sign it turns in to addition. For example +7 - (-7) = 14 and (-7) - 7 = (-14)
What are expressions and equations?
Expressions are mathematical combinations of numbers, variables, and operations (like addition or multiplication) that do not include an equality sign, such as (3x + 2). Equations, on the other hand, are statements that assert the equality of two expressions, typically featuring an equal sign, such as (2x + 3 = 7). While expressions can be simplified or evaluated, equations can be solved to find the value of the unknown variable.
Is 3 plus 7 a numerical expression?
Yes. Anything which you can evaluate (calculate) to get a number is a numerical expression. Thus, all of the following are numerical expressions:5x (if the variable stands for a number)1 + 25 / 3square root of (5 / 3)In general:* Any number* Any variable that stands for a number* An addition, subtraction, multiplication, division, or power that involves numerical expressions is again a numerical expression (as long as the operation makes sense - for example, you can't divide by zero)* Many mathematical functions, with a numerical expression as a parameter - for example, sin(5 + 3), ln(10), etc.
