Our notes for the week. The acronym DCMAM stands for
Don’t Call Me A Monster
. It also stands for the steps needed (in order) to whittle a “Monster” down to a 2-step equation (with which, the students are modestly comfortable).

What is a multi-step equation?
Multi-step equations are
algebraic expressions that require more than one operation
, such as subtraction, addition, multiplication, division, or exponentiation, to solve. It is important to know about the order of operations when solving multi-step equations.
What does identify mean math?
more …
An equation that is true no matter what values are chosen
. Example: a/2 = a × 0.5 is true, no matter what value is chosen for “a”
What is an example of a multi-step equation?
Example. Solve 3y+2=11 3 y + 2 = 11 . Subtract 2 from both sides
of the equation
to get the term with the variable by itself. Divide both sides of the equation by 3 to get a coefficient of 1 for the variable.
What are 2 step equations?
A two-step equation is
an algebraic equation that takes you two steps to solve
. You’ve solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.
What are the four steps for solving an equation?
We have 4 ways of solving one-step equations:
Adding, Substracting, multiplication and division
. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

What are examples of identities?
Examples of social identities are
race/ethnicity, gender, social class/socioeconomic status, sexual orientation, (dis)abilities
, and religion/religious beliefs.
What’s the difference between an equation and an identity?
Solving an equation means finding the value or values for which the two expressions are equal. This means equations are not always true. … An identity is an equation which is always true, no matter what values are substituted.
2 x + 3 x = 5 x
is an identity because 2 x + 3 x will always equal regardless of the value of .
