Only if we turn around, can we not lose our children.

All the concepts from primary school to junior three!

Even this has been sorted out!!

The area of the triangle = bottom * height 2. Formula S= a * H H 2

The area of a square = side length * side length formula S= a * a

The area of rectangle = long * width formula S= a * B

The area of parallelogram = bottom * high formula S= a * h

The area of trapezium = (bottom + bottom) * Gao Gao 2 formula S= (a+b) H H

The interior angle and the inner angle and =180 degree of a triangle.

The volume of cuboid = length * width * height formula: V=abh

The volume of cuboid (or cube) = bottom area * height formula: V=abh

The volume of the cube = the length of the edge, the length of the edge, the formula of the length of the edges: V=aaa

The circumference of a circle = the diameter * PI formula: L= PI d=2 PI R

The area of a circle = radius * radius * PI formula: S= PI R2

The surface (side) area of a cylinder: the surface (side) of a cylinder is equal to the circumference of the bottom. Formula: S=ch= PI dh=2 PI RH

The surface area of a cylinder: the surface area of a cylinder is equal to the circumference of the base and the area of the circle at the ends. Formula: S=ch+2s=ch+2 PI R2

Cylindrical volume The volume of a cylinder is equal to the bottom area. Formula: V=Sh

The volume of the cone is =1/3 bottom and the height is higher. Formula: V=1/3Sh

The rule of addition and subtraction of fractions is the addition and reduction of fractions with the denominator, which only adds and subtracs the molecular phase and the denominator remains unchanged. The fraction of the denominator is added and reduced, first dividing, then adding and subtraction.

The rule of multiplication is to use a product of molecules to make a molecule and use the product of denominator as the denominator.

The division rule of fractions is divided by a number equal to multiplied by the reciprocal of this number.

Reading comprehension will apply the following definition of the formula of theorem property.

Arithmetic aspect

1, the addition exchange rule: the two numbers add the position and the invariance of the plus number.

2, additive combination law: add three numbers together, first add the first two numbers, or add the first two numbers first, then add the third numbers together, and remain unchanged.

3, multiplication commutative law: two numbers multiplication, exchange factor's location, product invariable.

4, multiplication combination law: three numbers multiplied, first multiplied the first two numbers, or multiplied the first two numbers first, then multiplied by third numbers, and their product remained unchanged.

5, multiplication distribution law: two numbers and the same number multiplied, can add two plus numbers with this number, and add two products together, the result remains unchanged.

Such as: (2+4) x 5=2 * 5+4 * 5

6, the nature of division: in division, the same multiplier is expanded and reduced simultaneously by divisor and divisor. O is O divided by any number that is not O.

Simple multiplication: multiplier and multiplier have O multiplication at the end, you can first multiply O, zero does not participate in the operation, there are several zeroes falling, adding at the end of the product.

7. What is equality? The value on the left side of an equal sign equals the value on the right side of an equal sign.

It's called equality.

The basic property of equality: the two sides of the equation are multiplied by (or divided) by one same number simultaneously.

The equation is still in place.

8. What is an equation? A: an equation containing unknown numbers is called an equation.

9, what is the equation of a dollar? A: an equation containing an unknown number and the number of unknown times is once.

Learn the example and calculation of the equation of one dollar. That is to say, there is a formula for calculating the number of generations.

10, score: divide the unit "1" into several parts on average, indicating that such a fraction or a fraction is called a fraction.

11, the rule of addition and subtraction of fractions: add and subtract fractions from the denominator, only add and subtract the denominator, and the denominator remains unchanged. The fraction of the denominator is added and reduced, first dividing, then adding and subtraction.

12. Comparison of the size of fractions: compared with the fractions of denominator, the molecules are large and small. The fraction of the denominator is first divided and then compared; if the molecule is the same, the denominator is smaller.

13, fractions multiply by integral product of fractional molecules and integers, and denominator remains unchanged.

14. The fractional multiplication fraction is the product of molecular multiplication and the product of denominator multiplies as denominator.

15, the fraction divided by integer (except 0) equals the fraction multiplied by the reciprocal of the integer.
