Exercise+1

**EXERCISE 1** //**Sequential structures: __put statements & math expressions__**// Turing processes mathematical expressions in the following order:


 * **P** || **Parentheses** || **** ||
 * **E** || **Exponents** || **x****y ||
 * D || Division || x/y ||
 * M || Multiplication || x*y ||
 * A || Addition || <span style="display: block; font-family: Arial,Helvetica,sans-serif; text-align: center;">x+y ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">S || <span style="display: block; font-family: Arial,Helvetica,sans-serif; text-align: center;">Subtraction || <span style="display: block; font-family: Arial,Helvetica,sans-serif; text-align: center;">x-y ||

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">When you combine a put **statement with a mathematical expression such as** put 4 + 5 **the result of the expression will be output to screen:** 9

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">**Their are two special operators used in programming that you might not see elsewhere:** mod **mod (modulus) divides a number and returns the remainder, i.e., 3 mod 2 = 1** div **div divides the number and returns the quotient, i.e., 5 div 2 = 2**

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Task: **Complete the following exercise in your notebook. Write the expression in Turing required to evaluate the following statements and record the resulting answers in you notebook.**


 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Expression || <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Expression in Turing || <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Answer ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">1.4 + 3 * (5/2) ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">63 +5 *8*4 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">the square root of 64 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">1/3 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">1 + 2 –4 * 5/6 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">the quotient when 10 is divided by 3 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">the remainder when 28 is divided by 9 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">17 *(99 div 7) +99 mod 7 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">4 [(12*5/2)/5] mod 5 ||  ||   ||
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">52 (12 mod 3) mod 2 ||  ||   ||

Make certain you understand the difference between __mod__, __div__, and regular division**
