Writing Integers with Positive and Negative Signs
Writing integers with positive and negative signs is a Grade 6 math skill in Big Ideas Math Advanced 1, Chapter 6: Integers and the Coordinate Plane. Students learn to use the + sign for positive integers and the - sign for negative integers, understanding that whole numbers without a sign are positive by convention, and that zero is neither positive nor negative.
Key Concepts
Positive integers can be written with or without a positive sign: $+5 = 5$. Negative integers must always be written with a negative sign: $ 3$. Zero is written without any sign: $0$.
Common Questions
How do you write positive and negative integers?
Positive integers are written with a + sign or no sign at all (e.g., +5 or 5). Negative integers are written with a - sign before the number (e.g., -5). Zero has no sign and is neither positive nor negative.
What are integers in Grade 6 math?
Integers are the set of whole numbers and their negatives: {..., -3, -2, -1, 0, 1, 2, 3, ...}. They do not include fractions or decimals.
How are positive and negative integers used in real life?
Positive integers represent quantities above a reference point (temperature above zero, floors above ground, money earned), while negative integers represent quantities below (temperature below zero, floors below ground, debt).
Where is this skill taught in Big Ideas Math Advanced 1?
Writing integers with positive and negative signs is covered in Chapter 6: Integers and the Coordinate Plane of Big Ideas Math Advanced 1, the Grade 6 math textbook.
