Subtract. $$ -71-2 $$

Short Answer

Expert verified

-73

Step by step solution

Identify the Operation

The task is to perform the subtraction operation between two numbers: $-71 - 2$

Rewrite the Expression

Note that subtracting a positive number from a negative number is equivalent to adding the negative of that number. Rewrite the expression as follows: $-71 - 2 = -71 + (-2)$

Perform the Addition

Now add the two negative numbers: $-71 + (-2) = -73$

Final Answer

The result of $ -71 - 2 $ is $ -73 $.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Subtraction of Integers

Subtraction of integers is one of the basic arithmetic operations. It can sometimes be a bit tricky, especially when dealing with negative numbers. Let's break it down step by step. If you're subtracting integers, you are essentially finding the difference between two numbers. When both numbers are negative, subtracting the integers involves adding their absolute values together and then keeping the negative sign. For example, in the expression $-71 - 2$, you rewrite it as \-71 + (-2)\. This approach simplifies the process and makes it easier to understand.

Negative Numbers

Negative numbers are numbers less than zero. They are represented with a minus sign (-) in front of the number. Understanding how to work with negative numbers is crucial for solving arithmetic problems. When you have two negative numbers, you can think of it visually as moving further away from zero on the number line. If you subtract a positive number from a negative number, you are actually moving further into the negative. For instance, $-71 - 2$ is the same as saying we move 2 more steps to the left from -71, landing us at -73. This visual aid can help in grasping negative numbers better.

Basic Mathematics

Basic mathematics involves fundamental operations like addition, subtraction, multiplication, and division. These are the building blocks of higher-level math. Subtraction, in particular, involves finding the difference between two numbers. It is essential to remember the rule that subtracting a number is the same as adding its opposite. Practicing with simple problems, such as the one solved here, helps in strengthening your foundational skills, allowing you to handle more complex mathematical concepts with ease.
