Step 5: multi-task download framework and multi-task framework

If you think Stay sends a soft article every day, stop paying attention to it. If you still have obsessive-compulsive disorder, you have to make efforts to click my new push. I think I am guilty. In fact, it doesn't matter if I buy a course that doesn't buy Stay. Originally, my feelings are worthless.

Actually, the most valuable things of each course are for free. From the flowchart to the design and implementation methods, what functions are available and what can be expanded. All of these have been said. Why do we need to see the code. If it was really smart, Stay said the solution, and Nong was able to cut his foot.

Multi-task download is required by many apps, and many services are centered around downloads. App market, music download, video download, and offline news. It is not necessary for an interview.

Of course, it's not just for the interview. I hope you can free yourself from repetitive labor, whether it's new technology or spending more time with family members and sisters.

Watch the video for about 20 minutes.

7. Knowledge Framework of Unit 5, mona1 Equation

First mathematics volume: one-dimensional equation
[Part 1] Knowledge Point Distribution
1. solution of one-dimensional equation (emphasis)
2. Application of One-dimensional equations (difficulties)
3. Solving the one-dimensional Equation and Its Application to practical problems (test site)
[Part 2] handout on one-dimensional equation

1. One-dimensional equation
(1) Equations containing unknowns are equations.
(2) There is only one unknown (yuan), and the number of times of the unknown is 1. The equation is called a one-dimensional equation.
(3) analyzing the quantitative relationship in the actual problem and using the equivalent relationship to list the equation is a mathematical method to solve the actual problem.
(4) Steps for solving the actual problem of the column equation: ① set the unknown number; ② find the equivalent relational column equation.
(5) Finding the value of the unknown that makes the values on both sides of the equation equal is called the solution of the equation.
(6) the process of solving the equation is called solving the equation.

Ii. Properties of Equations
(1) the equation that represents the equality relationship with the equal sign "=" is called an equation.
(2) properties of equations 1: the results are still equal by adding (or subtracting) the same number (or formula) on both sides of the equations.
If a = B, a ± c = B ± c.
(3) Equality 2: The two sides of the Equation multiply the same number, or divide by a number not 0, the results are still equal.
If a = B, ac = bc;
If a = B and c = 0, then.
(4) when using the equations:
① Both sides of the equation must be involved in the operation and perform the same operation; ② the two sides of the equation must be added or subtracted, and the number of multiplication or Division must be the same number or the same formula;
③ Neither side of the equation can be divided by 0, that is, 0 cannot be a divisor or denominator.
Iii. solution of one-dimensional equation
1. Solving a one-dimensional equation -- merging similar items and moving items
(1) basis for merging similar items: Multiplication distribution law. The function of merging similar items: it is a constant deformation that acts as a "simplification", which makes the equation simple and closer to the form of x = a (a is a constant.
(2) Change a number on one side of the equation and move it to the other side.
(3 ). assignment basis: Properties of equations 1. the function of moving items: By moving items, the items with unknown numbers and constant items are respectively located on both sides of the equation, so that the equation is closer to the form of x = a (a is a constant.

2. Solving the one-dimensional equation-de-parentheses and de-denominator
(1) Multiply the two sides of the equation by the minimum public multiple of each denominator so that the equation does not contain denominator. Such deformation is called denominator removal.
(2) downstream speed = hydrostatic speed + water flow speed; reverse flow speed = hydrostatic speed-water flow speed.
(3) total work volume = work efficiency × work time.
(4) Workload = per capita efficiency × Number of people × time.

Iv. Actual Problems and one-dimensional equation
(1) The actual selling price refers to the actual selling price of the product.
(2) The purchase price refers to the price from the wholesale department or manufacturer. The purchase price refers to the purchase price of the product, also known as the cost price.
(3) The price indicates the original price of each item marked by the merchant. It is different from the price. It refers to the original price.
(4) A discount refers to the fact that the original price is multiplied by a few or a few percent.
(5) Profit and Loss: profit = price-cost; Price = Price + profit x profit margin;
(6) Oil Production = rapeseed yield × oil content × planting area.
(7) Application: Travel problem: distance = Time X speed; engineering problem: total workload = work efficiency x time;
Savings profit: Interest = Principal × interest rate × time; principal and interest = Principal + interest.
