ARITHMETIC PRACTICE PROBLEMS

There are several different solutions per problem!

Convert the following COMPUTE statements into an equivalent group of ADD, SUBTRACT, MULTIPLY, and DIVIDE statements

*********************************************************

COMPUTE Z ROUNDED = A * B / C – D

Multiply A by B

Divide B by C giving C (or divide C into B giving C)

Subtract D from C giving Z rounded

*********************************************************

COMPUTE K = I – ( J / L + M) / P

Divide J by L giving J

Add J to M

Divide M by P giving P

Subtract P from I giving K

*********************************************************

COMPUTE T = S ** R (hint: needs a perform statement)

Move 2 to x

Move s to t

Perform until x > r

Compute t = t * s

Add 1 to x

End-perform

*********************************************************

Convert the following groups of add, subtract, multiply, and/or divide statements to one COMPUTE statement

*********************************************************

ADD A B TO D

SUBTRACT F FROM D

MULTIPLY G TIMES D GIVING H

COMPUTE H = ((A + B + D) – F) * G

*********************************************************

DIVIDE A BY B GIVING C

ADD A C TO D

DIVIDE E INTO D GIVING F

SUBTRACT G FROM F

COMPUTE F = ((A + A/B + D) / E) - G

*********************************************************

MULTIPLY A BY B ROUNDED C

ADD B C TO E F

SUBTRACT E F FROM G

CAN’T!!! i.e. convert to ONE compute statement because of the rounded!

COMPUTE c rounded = a * b

compute g = g - (b+c+e + b+c+f)

if the C was not rounded in the first statement i.e. the multiply statement, then the C in the second compute would be replaced by a*b
