Expressions are problems that have no equal sign like a statement
Term in which the variable is the same
What are the characteristics of like terms?
exponats and variables
Combining like terms
What terms can we combine?
Like terms can be combined because the like terms are the same value
What terms can we NOT combine?
We can't combine non like terms because the values are unknown and different.
One step equations
What are they?
One step equations are when you only have to add, subtract, multiply or divide one in one equation
How do we model them?
Modelling one-step equations involves representing real-world situations using mathematical expressions with a single operation.
How do we use the model to solve one step equations?
I need to isolate the variable by following certain steps
How do we solve them?
Solving one-step addition equations involves isolating the variable by performing the inverse operation of addition.
