Hello, can you help me come up with some off form calculation problems, all simplified, simpler, tha

Off-form calculations 5 1 4 3 5 1 4 3

Solution: Four rules of operation (calculated in order, multiplication and division first, then addition and subtraction, parentheses are counted first, and power is calculated first), that is, the off-form operation (recursive equality calculation) needs to be carried out under the premise of this principle. Problem solving process:

Extended information (reduction process): The basis for judging whether the fraction is the simplest fraction can be based on whether the common factor of the numerator and denominator is only 1, if only Xuchang has 1, the fraction is the simplest fraction, and vice versa; If the numerator and denominator are decimals, they can be determined after the whole is carried out.

Problem solving process: Because the common factor of the denominator of the numerator is [1]16 9: It is already the simplest fraction and does not need to be simplified.

If you have any doubts, please ask and be satisfied.

This is the addition of fractions with different denominators.

First of all, it is necessary to make a general score.

Convert three fractions into fractions with the same denominator.

Calculate again.

Off-form computing is a mathematical term, that is, recursive equation calculation, the operation of writing the calculation process in its entirety, that is, the calculation that is out of the vertical form.

1) 50-50x24÷80

2) 30x(125-100÷25)=30x(125-4)

30x121

The part of the first parabola above the x-axis is y = (2x), and the part below the x-axis is y = - 2x) The line x = 1 2 intersects the parabola at a(1 2, -1) at x (0 < x < 1 2): the rotating body is a torus with an inner diameter of r = - 2x) -1) = 1 - 2x) and an outer diameter of r = (2x) -1) = 1 (2x) cross-sectional area s = r -r = 4 (2x) The volume is an integral of s from 0 to 1 2, and the result is 4 3

The second question.

I didn't ask that.

Sorry dear, I was wrong about the second one.

I'll do the math for you.

The third question is not an odd function, how can it be 0

SIN minus 2 is also 0

Question: But this is a point, which must be greater than zero.

The area above the x-axis minus the area below the x-axis.

If the area above is equal to the area below, it is zero.

Question: There is no area below the x-axis, how does the square sum exponent appear below the x, answer the third question you do, you can directly let x equal to 2/2, minus x equals minus minus 2/2 This is OK.

Ask okok, how to calculate the second question.

The second option D is incorrect, and the choice A is incorrect

I suddenly understood the second type of question, thank you.

2.（58+37）÷（64-9×5）

48.-3x+2y-5x-7y

48.-3x+2y-5x-7y

48.-3x+2y-5x-7y

What is the difference between 1 8 and 5/3 minus the sum of 3 and 4/1 and 1/1 and 3/10?

2 The number A is 1/4 and 1/5, which is 5 times less than the number B.4 5.

3 A number is more than the sum of 4 and 1/2 2 and 1/4, find this number.

Hope it helps!!
