2c 2(5) 10 The answer is 10. You plug in the value of 5 for c. When the number and variable touch directly it implies multiplication.
32
It is an equation in a single variable, x.
It is an equation in the variable r.
a( 10 ) - b( 5 ) = 5 ?
The equals operator is used for assigning a value to a variable. ex String name = "efu"; the equals equals operator is used for comparaing if the given value is equal to another value which is assigned for a variable. ex int i = 0; int j = 5; if( i == 0){ System.out.println(j+"can't be divided by"+i); }else{ System.out.println("answer is " +j/i); }

x = -5
One equals is used in an equation which is true, such as 5 + 3 = 8 Equals equals is used in computer programming as a question as to whether 2 things are equal. Like If x == 4 perform this operation ... If you are referring to 'C' language programming: A single equal sign is an assignment, a double equal sign is a comparison. a = 7; /* An assignment. You are assigning the value of 7 to the variable called 'a' */ if (a == 7) /* A comparison. You are checking if the variable 'a' has the value of 7 */

In C: x = 5 always means assign the value of 5 to x; x == 5 always means compare the value of x with 5.
