Create a BEDMAS Problem using every numbers 1-9 with Brackets, exponents, division, multiplication, addition and subtraction. They must equal 7.

I hope it helps you.

Order Of Operations - B.E.D.M.A.S

The Languages Of Math

B.E.D.M.A.S has different meanings

B - Brackets ( )
E - Exponents
D - Division
M - Multiplication
A - Addition
S - Subtraction

Did you know?

Division and multiplication goes from left to right, and same with addition and subtraction.

Example:
2+3x4=14

2+3x4=
2+12=
14=

Corrections to number 2

Indicate whether the statement is true or false.

Translations, rotations , and reflections change the size of the sides or angles of the orginal figure.

Answer: False

Explanation: Because you are only moving the original figure, by sliding it reflecting it or rotating it, but the figure stays the same.

Pictures of Translation , Reflection , and Rotation.

Rotation

Rotations can be clockwise or counterclockwise. A rotation can be turned or rotated by degrees such as 90 degrees 180 and 360 degress. But every rotation has a centre of rotation. The centre of rotation is mostly located on the the origin.



The origin is located in the middle of the vertical and horizontal number line. You can also call it (0,0) in the coordinate grid.
