There are infinitely many expressions for the number 7, as it can be represented in various mathematical forms. Some examples include 7, 3+4, 10-3, 14/2, 2^3, and sqrt(49). These expressions can involve addition, subtraction, multiplication, division, exponentiation, and square roots, among others.
Multiplication and addition.
When you have a negative number after the subtraction sign it turns in to addition. For example +7 - (-7) = 14 and (-7) - 7 = (-14)
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.
9+8+7+65+4+3+2+1 = 99. So 7 addition signs need to go in 987654321 to get a total of 99.

9(n +7)
Additive inverse of a number a is that number which on addition with a gives 0.7 is additive inverse of -7.The property shown is additive inverse property because the addition yields 0.
9+7
70 + 7
Yes. Anything which you can evaluate (calculate) to get a number is a numerical expression.

1+7= 2+6=
9+8+7+65+4+3+2+1 = 99. So 7 addition signs need to go in 987654321 to get a total of 99.
make it a '+ negative number'. Example: 6 - 7 = -1 6 + (-7) = -1
In Chemistry, the family number tells you how many electrons the element gives, gains, or shares. It also tells you how many valance electrons you have. In addition and subtraction, number families include two lesser numbers and one greatest number (also called the smaller and larger numbers) such as 4+3=7 and 7-4=3
