### Bite Size Practice Additional Mathematics #20 (Indices Application of Exponentials)

Another set of Questions with Answers for Indices with Differentiation in it. This A Math question is an application question about radioactive substances and has a decay rate. We can find the time for half mass and rates of change using the techniques taught here. Using differentiation, we can solve sums ob how fast the substance decreases at a particular time. First thing is to have all the information written down, then like a jigsaw puzzle, put it in its place and use algebra, indices and logarithm. For this question, we tried really hard to help by including hints to all the answers to the questions. Also, check out how the flow works in the answers given, it helps to put the workflow into perspective. Make sure you understand your Indices and Differentiation lessons before attempting this question. Enjoy!

Our Singapore Maths lessons will be engaging our students to be learning A Maths in a fun way and shall be beneficial to their school work. We don’t rest on our laurels as years roll past because we know what is taught is just going to go faster, so we adapt and we keep ourselves at the forefront with our Math classes. Teaching ahead of all schools are our priority and helps Math students to be confident and have clarity in school lessons. Knowing they have learnt the best techniques augments confidence. Having a candid mindset to what lies ahead helps us to plan and solve our Math student’s problems as we know the requirements for them to do well individually and to do Math with efficiency.

Mentoring students to be good in Mathematics also requires us to be their confident ally and have them actively engage in our Math tutorials. Resolving doubts, fears and any variables during class helps our Math students to be calm and resolute. Power comes from the ability to control emotions, and to solve questions in a stressful examination. During class, students will get a chance to do sums that ramps up in difficulty until they get overstretched. Then we’ll pull a safety net out for them to fall softly and we’ll run through those questions. Every question gets its day, explained to full understanding, worked till no one misunderstands it. Active learning and making mistakes creates experience. Know where one can fall, get it horribly wrong in the safety of our Math tutorial emulates how one can go wrong in examinations before attempting one.

Our Add Math classes requires the constant improvement needed to keep ahead of the pack requires us to evolve our A Math teaching skills to suit our student’s needs. Parents will be astonished at how much more work and complexity our education system has incorporated when they look at their kids textbooks. Times have changed. Schools teach at least 1 year faster now than 10 years ago. What used to be in Sec 2 is now taught in Sec 1. In fact, for A Math, some of the topics are from GCE A’ levels. Plus, it depends on the schools as well, with some advanced schools doing 2 years ahead of schedule to keep their students on their toes.
