) Melissa has invested a huge amount of money into the stock market. She doesn’t trust just anyone to give her advice regarding the buying and selling information. Normally, before she will buy a certain stock, she must get input from three sources. The first source is Adam, a famous stockbroker. The second source is Mary, a self-made millionaire in the stock market, and the third source is Laura, the world-famous psychic. After several months of receiving advice from all three sources, she has come to the following conclusions: Buy the stock if Adam and Mary both say yes and Laura says no. Buy the stock if Laura and Adam say yes and Mary says no. Buy the stock if Laura says yes and Adam or Mary say no. All three sources say yes. Don’t buy otherwise. Use the following: A: Advice from Adam (0 for not buy, 1 for buy) B: Advice from Mary (0 for not buy, 1 for buy) C: Advice from Laura (0 for not buy, 1 for buy) X: Melissa decision (0 for not buy, 1 for buy) i)Construct a truth table to implement the logic function telling Melissa when to buy the stock. ii)Write the logic expression (SOP) from the truth table in (i).
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

why we need to put 0-7 values for A, I thought we only can use 0 and 1.
