About This Set
These 25 questions check the basic method in every topic of the chapter: BODMAS and decimals, fractions and continued fractions, square and cube roots, indices, surds, and the number identities. Most of them need one rule used correctly: "of" before ÷, a root by prime factors, the conjugate in the bottom. They come in mixed order, so name the topic before you start the working. Allow about 20 minutes and finish all of them before checking. With fewer than 20 right, reread the sections your misses came from, then move on to Practice Set 2.
