Trying to avoid this is near impossible. Trying to answer questions in mathematics also becomes difficult without a sound knowledge of negative numbers. Following the easy steps set out in this book, working with negative numbers becomes a breeze and as a result so does algebra, trigonometry, linear equations and all the other topics that require this knowledge.
