Subtracting numbers is one of the basic operations in math.
Firstly, the order of operations is as follows: PEMDAS or parentheses, exponents, multiplication, division, addition, then subtraction.
All of these are done in the exact order given above.
For example, given the equation (4 x 7) + (6 / 2) - 3^2 = ?
1. Parentheses
- Solve the equations within the parentheses first.
(4 x 7) + (6 / 2) - 3^2 = 28 + 3 - 3^2
2. Exponents
- Second, if there are any exponents, solve this.
28 + 3 - 3^2 = 28 + 3 - 9
3. Mulltiplication
4. Division
5. Addition
28 + 3 - 9 = 31 - 9
6. Subtraction
31 - 9 = 22
Answer: 22.

I think you meant to say the equation is
y = 2x² - 2x + 3
Differentiate both sides with respect to x :
dy/dx = 4x - 2
At the point (3, 0), the slope of the tangent line is dy/dx(3) = 4•3 - 2 = 10. Then the normal line to the curve at (3, 0) has slope -1/10.
Using the point-slope formula, the equation of the normal line is
y - 0 = -1/10 (x - 3) ⇒ y = (3 - x)/10

Answer:
3/16 gallons 0.1875 gallons
Step-by-step explanation:
To determine the number of wooden signs that can be painted with one gallon of paint, divide the total amount of gallons of paint by 16
Total wooden signs that can be painted with one gallon of paint = 3/ 16
3/16 can be expressed as a decimal by dividing 3 by 16
decimal = 0.1875 gallons
