What are integers in the context of IB MYP Mathematics?

In the IB MYP Mathematics curriculum, integers are defined as whole numbers that can be positive, negative, or zero. They do not include fractions or decimals. Integers are used to represent quantities in various mathematical operations and real-life situations, such as temperature changes or financial transactions.

How do you add and subtract integers?

To add integers, if they have the same sign, you add their absolute values and keep the sign. If they have different signs, subtract the smaller absolute value from the larger one and take the sign of the number with the larger absolute value. For subtraction, change the operation to addition and switch the sign of the second integer, then follow the rules for addition.

What is the importance of understanding integers in IB MYP Mathematics?

Understanding integers is crucial in IB MYP Mathematics as they form the foundation for more complex number systems and operations. Integers are used in algebra, coordinate geometry, and real-world applications like calculating elevations, financial accounting, and scientific measurements.

How do you multiply and divide integers?

When multiplying or dividing integers, if both integers have the same sign, the result is positive. If they have different signs, the result is negative. For multiplication, multiply the absolute values. For division, divide the absolute values, ensuring the result follows the sign rule.

What are some real-life applications of integers?

Integers are used in various real-life scenarios, such as representing temperatures above and below zero, financial gains and losses, and elevations above and below sea level. They are also essential in computer science for indexing and in sports for scoring systems.
