        Do you like to play with numbers? Solving number games helps to sharpen your brain. Let us have

        some fun with numbers.

        Let’s solve the following.

          1.  If + means ÷, × means –, – means ×, and ÷ means +, then 38 + 19 – 16 × 17 ÷ 3 = ?

               a.  16                  b. 19                    c. 18                   d. 12


          2.  If a means +, b means –, c means ×, and d means ÷, then 18c 14a 6b 16d 4 = ?

               a.  63                  b. 254                   c. 288                  d. 1208

          3.  If A means +, B means –, C means ×, D means ÷, then solve 100D 20C 3A 10B 5 = ?


               a.  15                  b. 25                    c. 30                   d. 20

          4.   If ÷ means ×, – means +, × means –, and + means ÷, then what will be the value of 20 + 4 × 6 – 5
              ÷ 7 = ?


               a.  28                  b. 32                    c. 34                   d. 36

          5.   If P means ×, Q means ÷, R means +, and S means –, then what is the value of 154Q 14S 7P 3R 25
              = ?

               a.  35                  b. 57                    c. 42                   d. 15


          6.   If P$Q means divide, P#Q means subtract, P%Q means add, P@Q means multiply, then 70# 30%
              80$ 20@ 10 = ?

               a.  60                  b. 80                    c. 20                   d. 10

                    Aryabhata  from  ancient  history  was  the  first  person  to  figure  out  that  the  moon  and
                    planets shine due to reflected sunlight. He also calculated the closest approximate value
                    of pi during that time and contributed to the fields of Algebra and Trigonometry.
