a. Evaluate the expression, 4 + 6 * 2
Operator Precedence:
An expression is a statement, which will hold a value when it is evaluated. A mathematical expression will hold multiple operators and grouping symbols; an expression will be evaluated based on the precedence of the operator. The rules of the operator precedence are given below.
- Unary negation (-) and brackets () will have the highest priority.
- Multiplication (*), division (/) and modulus (%) will have the next highest priority.
- Addition (+), subtraction (-) will have the lowest priority.
b. Evaluate the expression, 10 / 5 + 8

Draw flow charts for each of the following;a) A system that reads three numbers and prints the value of the largest number.b) A system reads an employee name (NAME), overtime hours worked (OVERTIME), hours absent(ABSENT) and determines the bonus payment (PAYMENT).arrow_forwardScenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you…arrow_forward
