W02 Math Exercises: Introduction to Addition and Subtraction

Math Exercises General Introduction

Imagine a piano teacher sat down and taught you the notes and how to count, then expected you to play a complicated classical piece of music. How would it go? Not very well, because you need practice. When learning to play the piano or any instrument, you start with the basics, learning a few notes at a time and practicing them over and over again. The more you practice the better your fingers and your brain become at recognizing the notes and playing them correctly. You may still make mistakes, but the more you practice the simple songs, the fewer mistakes you make. But once you master a simple song, are you ready to play the classical piece? No. You must continue to practice slightly harder and harder songs in order to get better and better at it.

Math is a skill like playing the piano. Just learning the concepts is not enough to apply them correctly. Practice is a key part of learning to do math. Each week you will have an exercise assignment due at the end of week deadline. It will contain many questions designed to help you practice the material you learned in the week. You may also see some review questions in future exercises. You can go through the exercises as many times as you like until the due date. Because of this, start early in the week if you feel you will need to take these exercises more than once. See the instructions below for more information about the due date.

Overview

This week, you learned about the different classifications of numbers, the number line, and adding and subtracting positive and negative numbers. Addition and subtraction are among the key fundamental concepts of math. This exercise will give you an opportunity to practice your addition and subtraction skills, especially with negative numbers. Having a strong grasp of addition and subtraction of negative numbers will help you throughout this course, especially when you get to algebra, and in life. You may want to practice adding and subtracting until you are proficient enough to do it quickly. One way to do this is to do this exercise more than once. Another traditional way is to use flashcards. There are also many apps that can help you practice this skill. But speed is not necessary to be good at math. Understanding is more important than speed.
