10 points! A few junior high school math fill in the blanks, will come!

Positive integers, zeros, negative integers.

Positive scores, negative scores.

Positive integers, zeros, negative integers, positive fractions, negative fractions.

Positive, zero. Negative, zero.

Negative integer, zero.

Positive integer, zero.

Rational number. Irrational numbers (is there a typo?) Is it "infinite non-cyclic decimal is")? Right?

Positive integers, negative integers, and 0s are collectively referred to as integers; Positive and negative scores are collectively referred to as fractions;

Positive integers, negative integers, 0, positive fractions, and negative fractions are collectively referred to as rational numbers;

Positive numbers and 0s are collectively referred to as non-negative numbers; Negative numbers and 0s are collectively referred to as non-positive numbers;

Negative integers and 0s are collectively referred to as non-positive integers; Positive integers and 0s are collectively referred to as non-negative integers;

Finite decimals and infinitely cyclic decimals can be considered as rational numbers; Infinite non-cyclic decimal multiplication is irrational.

It can be found in books, I hope you will learn about it.

1.-1,3

3.-4a b, -16, quadratic pentanomial, 3, 0, 3 (a-20), a+140

2*5=2-10=-8, the answer is -8

Connecting AB, then BAC+ ABE= C+ E

So connect the auxiliary line and you'll understand.

The interior is a pentagon, and the sum of the internal angles is: 5-2=3, 3*180=540°, and each angle forms a triangle with the two angles of the pentagram.

There are five triangles: the inner angle and 180*5=900° minus the pentagonal inner angle 900-540=360°.

But the apex angle of each pentagram is counted twice, so:

Position 3Not necessarily children will have to do it themselves next time.
