Start!!!
Compute: 1 + 2 * 3 = 3
Compute: 1 + 2 * 3 = 7
Compute: (1 + 2) * 3 = 9
Compute: 1 + (1/2) = 1.5
Compute: 1 + (1/3) = 1.3333333333333333
Compute: 1 + (1/3) + (1/2)= 1.8333333333333333
Finish!!!
Start Fraction!!!
Compute: 1 + 2 * 3 = 3/1
Compute: 1 + 2 * 3 = 7/1
Compute: (1 + 2) * 3 = 9/1
Compute: 1 + (1/2) = 3/2
Compute: 1 + (1/3) = 4/3
Compute: 1 + (1/3) + (1/2)= 11/6
Finish Fraction!!!
