LabSpace - The Open University Applying mathematics (Times Article) One of the questions every mathematics teacher is regularly asked is “When are we ever going to use these things?” This is probably the hardest question to answer in a satisfactory manner! We talk about the applications of mathematics in physics, engineering and computer science. It is today becoming more important for students to attain a higher level of numerical literacy - Christina Zarb Since I deal with many IT students, my favourite answer is “Google! Of course we can, many should be thinking. Mathematics is a compulsory subject throughout primary and secondary education – it is considered, and rightly so, a core subject throughout these highly important formation years, and a pass at Ordinary level is fundamental in order to continue one’s studies at post-secondary and tertiary level. After secondary school, students have to choose which combination of Advanced and Intermediate level subjects to pursue, keeping in mind the University degree they would like to read for.

Multiplicative inverse Number which when multiplied by x equals 1 The reciprocal function: y = 1/x. For every x except 0, y represents its multiplicative inverse. The term reciprocal was in common use at least as far back as the third edition of Encyclopædia Britannica (1797) to describe two numbers whose product is 1; geometrical quantities in inverse proportion are described as reciprocall in a 1570 translation of Euclid's Elements. In the phrase multiplicative inverse, the qualifier multiplicative is often omitted and then tacitly understood (in contrast to the additive inverse). The notation f −1 is sometimes also used for the inverse function of the function f, which is for most functions not equal to the multiplicative inverse. Examples and counterexamples In modular arithmetic, the modular multiplicative inverse of a is also defined: it is the number x such that ax ≡ 1 (mod n). These two notions of an inverse function do sometimes coincide, for example for the function where Complex numbers
