**Chapter 1 Grade 7 Integer Review:**

**Integers**are natural numbers (positive or negative) or zero.

**Brackets**are like training wheels.

For example; (-2) + 5 + (-7)

A

**zero pair**are any of the same number that has a positive and a negative that will equal to zero. For example: -2+2 = 0

Examples of

**Standard forms**:

4-5+6=5

-5-6=

4-5-7=

**Questions and Answers**:

-3-(-7)=4

-3-7=-10

3-7=-4

3+7=10

-3+7=4

**The great Big Book of Integers Chapter 2:**(+2)x(+3)= +6

(+2)x(-3)= -6

(-2)x(+3)= -6

(-2)x(-3)= +6

**Chapter 3; Dividing Integers**

**Partitive Division**is to divide something into parts. An example for it is;

**Sign Rule:**

- The quotient of two integers with the same sign is:
**positive**when even amount of "-" signs. - The quotient of two integers with different signs is: add number of "-" means
**negative**.

**Quotative Division** involves taking a set of size a and forming groups. (Sharing with groups)

eg.

Multiplicative Inverse to solve 6 ÷(-2)=;

**Chapter 4; Order of Operations with Integers**We solve this using B.E.D.M.A.S. (brackets, exponents, division, multiplication, addition, and subtraction)

(+5)x(-3)+(-6)÷(+3)=

(+5)x(-3)+(-2)=

(-15)+(-2)= -17
