CALCULATOR SKILLS !!!!!!!!!!!! PROBLEM 5.8 and 5.9

  1. PROBLEM FORMULATING SKILLS (TASK 1)

          IN GENERAL, it is harder to formulate a problem, than to solve it.

 

         N.B. This of course depends on the level of the problem.

 

Eg.  SOLVE without calculator:

 

          (a)      19386356 Χ 10983829

or      (b)      If three men can dig five graves in 2 days, how long will seven men take to dig 50 graves?

 

5. The word “more” is often confused. What is the difference between the two statements:

             (a) There are b boys and c more girls than boys; and

            (b) There are b boys and c girls, where the girls are more than the boys.

6. (a) What is wrong with the following proof of the statement: If n is even, then (-1) =1.

Proof:   (-1) = 1, and 4 is even, therefore (-1) =1.

7. State whether the following is true or false: 

(a)         60% of 90 = 90% of 60

(b)     of y expressed as a fraction of (a+b) =   of x expressed as a fraction             of (b+a).

8.  Refer Section 2.4.1 on p. 77 dealing with sets.  Draw a large, clear diagram, picture or any representation which represents the problem. (DO NOT SOLVE!!)

 

  1. NUMBER SYSTEM, CR p. 71
