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.

Since the ground floor has 52 windows, and every floor, here are 6 fewer windows than the floor below it, we make a expression.
52-y=x.
We are trying to solve for x, not y.
In order to get 'y,' you have to multiply 8 by 6. Which is going to be 48.
(If you don't know multiplication, respectively.)
So now that we solved for y, =48 .... 52-48= ....... = x
Now all we have to do is simply subtract.
x=4.
So the answer to the problem is 4 windows on the 8th floor.
Answer:
x=40
Step-by-step explanation:
Because every triangle's angles add up to 180 degrees, you know 3x+x+20=180. Since 3x and x are like terms, you can add them to get 4x. 20 and 180 are also like terms. However, to move your 20 to the side of 180, you need to subtract it. So you have 4x=160. To get x by itself, you divide 4x and 160 by 4. 4x/4 is x, and 160/4 is 40. So your answer is x=40.
Answer:
(2, 1 )
Step-by-step explanation:
Using the Section formula
For endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n
Then coordinates of point are
[ , ]
Here m = 5, n = 2, (x₁, y₁ ) = (- 3, - 9), (x₂, y₂ ) = (4, 5), thus partitioned point
= [ , ]
= [ , ]
= ( , )
= (2, 1 )
You’re solving for x, so the first step is to move all the x’s to the same side. Subtract 2x from both sides. You’re left with:
2x + 5 = -3
The x variable still isn’t by itself. Subtract five from both sides.
2x = -8
The last step to get x by itself is to divide both sides by 2.
Your final answer is: x = -4
