Data points that are not close to the line of best fit are called outliers.
The best way of answering this sort of question is to use a 24 hour clock as this allows simple subtraction. 6.30 pm in a 24 hour clock is 12.00 (mid day) + 6.30 = 18.30 18.30 - 08.30 = 10

OPERATION
Mathematical processes or operations
Addition and subtraction are examples of arithmetic operations, specifically binary operations. These operations involve combining two numbers to produce a single result. In mathematics, addition is considered an operation that combines two numbers to find their sum, while subtraction is an operation that finds the difference between two numbers. Both addition and subtraction are fundamental operations in arithmetic and are used extensively in various mathematical applications.
Because addition and subtraction in 2's complement representation do not need to care about sign.

There are a number of ways one can learn subtraction. Perhaps the best way is to find one that can spend some time teaching one subtraction. There are a number of workbooks also available.
A fact family is when the same 3 numbers are used in addition and subtraction sentences. An example would be 3+4=7, 4+3=7, 7-4=3 and 7-3=4
Any calculator having sturdy design , 10 digit large display and basic functions like addition, subtraction, multiplication, division, percentage and square root is good enough for elementary students.
Addition and subtraction are the only fraction operations that need a common denominator. Multiplication, division, and exponents do not need a common denominator. In fact, it is best to use reduced fractions otherwise it gets very messy.
It is best remembered by its acronym - BIDMAS (UK) or PEMDAS (US). B = Brackets (P = Parentheses) I = Index )E = Exponent) DM (MD) = Division and Multiplication, with equal priority, left to right. AS = Addition and Subtraction, with equal priority, left to right.
