 Discuss the language, symbols and conventions in mathematics Explain the nature of mathematics as the language Pergorm expressions on mathematical expressions correctly Acknowledge that mathematics is a useful language  is a system of communication using symbols or sounds there must be words or symbols must also have a set of rules to follow on how to make use of those symbols - a grammar or a syntax there should a group of people who understands and use these symbols  is a system used in the field of mathematics to communicate mathematical ideas, concepts and theories among others it is distinct and unique from the usual language that people are used to. used to communicate abstract and logical ideas  to be able to make very fine distinctions “accurate or exact” “The cat is in the mat. 25 > 29 230 degrees  used to refer Type equation here.certain quantities, concepts, ideas and others...  ten digits... 0, 1, 2,3,4,5,6,7,8,9 basic +, -, /, x operations sets U U U U variables a,b,c,.......x,y,z special , =, =,..... symbols  to write expressions and sentences briefly mathematical language is able to say or write things briefly we can convert mathematical language to expressions or equations ex. a. the sum of five and a number b. twenty-five times a number  mathematical language is a powerful tool because it can express complex thoughts with relative ease ex. a. “product of two numbers is equal to 51” it can be written as xy=51 b. work =? w=Fd  it is a mathematical analogue of an English noun DOES NOT state complete thought the most common expressions are numbers, variables, sets and functions 5 9x a-4 x/4 y+21  it is a mathematical analogue of an English sentence state a complete thought the most common expressions are numbers, variables, sets and functions 5 + 21 = 26 9x=18 a-4>16 always used relation symbols = , >, <... etc  have verbs in 5 + 21 = 26, the verb is “=” mathematical sentence can... 1.always be TRUE 2. always be FALSE 3. sometimes TRUE / sometimes FALSE  Identify if it is Expression or Sentence 1. x+2 6. 1+2+3+4 2. 5x=25 7. x+5=13 3. 2+5=√49 8. a2+b2=c2 4. 234-100=143 9. 5 5. 2x 10. 2x
