A. B. C By Jon Parkinson

Algebra

I learned how to use BEDMAS to solve algebra questions in order to get the correct answer.

Example:

5x + 3(3x + 2) – 45x + 9x + 6 – 4 Brackets14x + 6 – 4 Addition14x + 2 Subtraction

Brackets

I learned that two brackets together or having no sign between a number and a bracket means to multiply.

Example:

(23 + 4)(13 – 5)27 x 8

Or3(21 – 3)

63 – 9

Coefficient This year I learned that Coefficient is the

number in front of an variable Example:

3xVariable

Coefficient

Divide I learned this year that two negative

numbers with give you a positive number, because

- 3 -7 +21

Exponents

I learned that having two exponents, one in a bracket and one outside a bracket implies that you have to multiply them together, because there are however many copies of that bracket which includes coping the exponent in the bracket

(3 )

3 4 12

3

3 4

12

Fraction

I learned this year that fractions and ratios are the same thing just written in different way

1:4 = ¼

Graphs I learned this year that the number in a X and Y table can be put

into a graph

X Y

1 3

2 7

3 11

cHord I learned that a chord is a vital part in finding the

center of a triangle if it is not marked for you. A chord and a perpendicular bisector and another one of these in a different place will find the center of the triangle.

Integers

I learned this year that integers are are numbers that does not use decimals, fractions or other symbols with the number.

Example: 9.45 and ¼

Just do it

I learned that when you times fractions you don’t need to find a common denominator you just do it

½ x ¾ 1 x 32 x 43/8

Keep Change flip I learned this year that when dividing fractions you keep the first

fraction change the division symbol to a multiplication and flip the fraction so the numerator is now the denominator and the denominator is now the numerator.

¾ ½¾ 2/1

Linear relations

I learned this year that linear relation represents a pattern that can be found by using a formula.

Models I learned how to modeling can help

visualize an equation that is hard to picture in your head.

Numbers I learned this year that there are

negative numbers and not just positive numbers on a number line.

Order of operation

I learned that Order of operation (BEDMAS) is an easy way to solve question without lots of effort

5x + 4(3x + 2) – 45x + 12x + 8 – 4 Brackets17x + 8 – 4 Addition 17x + 4 Subtraction

Polynomials

I learned this year that polynomials are you just variables in an equation.

Quotient

I learned this year that Quotients can vary between many types of numbers including variables

Example:

AB/X = X/Bx X x XAB = BB = AB

Ratio I learned this that a ratio is a scale stating that if

the right is 1 and the left is 4 the object is getting 4 times smaller. But if it is 4:1 than it is getting larger.

Subtraction

I learned this year that subtracting a negative number will give you a positive because your taking away from a negative number.

Example:

Triangle I learned this year that all the angles in a

triangle will always equal 180 degrees for all the different types of triangles

Units

I learned this year that units are the measurements given to an object with no measurement.

Example:

5 x 6 = 30 units

Variables

I learned this year that Variables replace any unknown numbers that are in an equation.

Example:

? x 3 = 9 x ? + 4A x 3 = 9 x A + 4

Whole Numbers

I learned this year that whole numbers are exactly the same as integers in the fact the they both are numbers that don’t use decimals and fraction.

Example: 4.56 and ½

X axis

I learned this year that numbers on the x axis and y axis are patterns that are found by a formula in a table.

X Y1 32 63 9

Y axis

I learned this year that numbers on the x axis and y axis are patterns that are found by a formula in a table

Zero pairs I learned that during algebra zero pairs is a way of

getting rid of a number so we can isolate the variable.
