A comprehensive course designed to build foundational and advanced math skills for 6th-grade students, preparing them for the MAP assessment and real-world problem-solving.
An expression is a mathematical phrase that combines numbers, variables, and operations, but does not have an equal sign. For example, \(3x + 5\).
An equation shows that two expressions are equal, using an equal sign. For example, \(3x + 5 = 20\).
To find the value of a variable that makes the equation true, use operations to isolate the variable.
Expressions and equations help us figure out unknown values, like the cost of items or solving for missing information in puzzles or games.
Solving equations is used in budgeting, dividing up chores, or planning trips.
\(2x + 4 = 12\) can be solved to find \(x = 4\).
If you have \(5n\) candies and give away 10, you can write the equation \(5n - 10 = 15\) to find out how many candies you started with.
Expressions are math phrases; equations show that two things are equal and can be solved.
