Pre-Algebra: Chapter 3, Lesson 6 One step inequalities We solve one step inequalities just like we do for equalities. Just substitute the sign with an equal sign. Solve the problem with the equal sign and once you have the solution, … Continue reading →

Pre-Algebra:Chapter 3, Lesson 4 (yesterday, October 9) Formulas Using the formulas given, like the “DRT” one (distance = rate * time) where another word for rate is the SPEED, you just plug in (via the “Glade” commercial) the stuff that … Continue reading →

Pre-Algebra: Chapter 3, Lesson 3 1 step equations using multiplication and division Just like we did with 1 step equations using addition and subtraction, we can do the opposite of the operations to isolate the variable. If it is a … Continue reading →

Pre-Algebra: Chapter 3-2 Solving one step equations Equations have to have an equal sign with variables and numbers known as constants. To solve 1 step equations, we are going to isolate the variables on one side and the constants on … Continue reading →

Pre-Algebra: Chapter 3, Lesson 1 Eliminate possible solutions when problem solving by trying an answer and see if it works, or building a diagram or picture and eliminating items that the evidence tells you are false. BIG HINT: Problem number … Continue reading →

Pre-Algebra: Chapter 2-8 Dividing Integers Using the same rules as multiplication except in reverse, we know how to calculate division. Just remember, that the quotient of two integers with different SIGNS is NEGATIVE. Simple rule! Algebra: Chapter Review We spent … Continue reading →

Pre-Algebra: Chapter 2-7 Yesterday we worked on multiplying rationale numbers. Easy rules: positive * positive = positive negative * negative = positive negative * positive or positive * negative = negative! Algebra: Chapter 2-10 Yesterday we skipped lesson 2-10 and … Continue reading →

Pre-Algebra: Chapter 2-6 We are working on progression, both arithmetic and geometric. Arithmetic progressions have patterns that we can either add or subtract from/to. 0, 5, 10, 15, 20 is an example. We add 5 to each number. Geometric progressions … Continue reading →
