What are relational operators?

• They allow for assignment and for comparisons to be made

• They do Maths.

• They are all Maths symbols.

• They give us an answer to an equation.

Where might we use relational operators?

• They are used in condition testing such as IF statements and loops.

• They are used in equations where we need a value.

• They allow us to do mathematics in functions.

Which of the following are Boolean operators?

• NOT, AND, OR

• IF, WHILE, DO WHILE

• IF, ELIF, ELSE

• FOR, WHEN, THEN

What are arithmetic operators?

• They allow numerical operations to be performed on values.

• They allow for assignment and for comparisons to be made.

• They test for true and false situations.

Which of these are arithmetic operators?

• /, *, +, %

• AND, NOT, OR

• ==, !=, <=

What am I?

To find a number, you halve the data set repeatedly until what you are looking for is found. You will use a comparison of less than or greater than until the number found is equal to.
