The One-step equations with addition and subtraction exercise appears under the 6th grade (U.S.) Math Mission, 7th grade (U.S.) Math Mission, Algebra basics Math Mission, Algebra I Math Mission and Mathematics II Math Mission. This exercise has one-step equations involving addition and subtraction.
Types of Problems
There is one type of problem in this exercise:
- Solve the given equation: This problem provides an equation that requires one operation to solve. The user is expected to find the correct answer and type it in the space provided.
- When an addition problem is given, subtraction solves for the variable. Subtraction is non-commutative so care needs to be taken with the order of subtraction.
- When a subtraction problem is given, addition solves for the variable. Addition is commutative so order is irrelevant.
- It can be faster if one can recognize the number that needs to replaced in the equation to make it true.
- Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
- An ability to find the steps and the instances of error is a skill that is useful in teaching.
- Linear equations, as the initial stage of polynomials, have many applications in several fields of study.
- Equations show up in nearly every science or business class one is ever in.
- Computers are also equation solvers. Computers were originally invented to solve equations over and over again instead of humans doing the calculations.
