Math Expression Exercises: (DO ALL 8 PROBLEMS FOR BOTH SETS OF EXERCISES)

 

 

EXERCISE SET 1: Provide the correct result by evaluating the following expressions:

Consider the variable A to have the constant value of 5 and B to have the constant value of 8.

 

 

1.   8 + 5 - 3                         _______________________

 

 

2.   5 - 6 * 3                         _______________________

 

 

3.   9 / 3 + A - 2                     _______________________

 

 

4.   4 + (6 * A - 3) - 2               _______________________

 

 

5.   B * 3 - 7                         _______________________

 

 

6.   B * (3 - 7)                       _______________________

 

 

7.   (4 * 2)  /  (3 - -1)              _______________________

 

 

8.   (A+ A + 50) /  3 * (B - A)        _______________________

 


EXERCISE SET 2: Assigning Values to Variables:

 

What are the values of A and B after these sequences of assignments?  Note: there is only one value allowed in a variable at a time.  Old values are erased by each new assignment.

 

1)

A = 5

B = 6

A = B              A:___________      B:________________

 

 

2)

A = 7

B = 18

A = B – 9          A:___________      B:________________

 

 

3)

B = 5

A = 5

A = B – A

B = A              A:___________      B:________________

 

 

4)

A = 0

B = A

A = 17             A:___________      B:________________

 

 

5)

A = 10

B = 5 + A * 2

A = 11             A:___________      B:________________

 

 

6)

A = 0

B = 4

A = B – A * 8      A:___________      B:________________
