This document contains a math problem involving classifying different types of numbers and performing calculations with integers, rational numbers, whole numbers, and natural numbers. It asks the reader to: 1) Classify various numbers into the different number categories, identify numbers that don't fit into any category, and draw a map showing the relationships between the categories. 2) Write out the first line of operations and results in English for 4 calculations involving integers, rational numbers, parentheses, and order of operations.

1. NUMBERS
1. a) Classify the following numbers placing them in every category they belong to. Circle the
numbers you can't place in any category. What are them?

b) Write three more numbers in each category.
c) Draw the categories as boxes in a map below these lines showing the relations between them like
we did in class. Place the numbers given in the “smallest” category they belong to.
2. Find out the result. After that, write out the first line of operations and the result in English:
Example: 2−(3−6)+5=2+3+5=10
Two minus parenthesis three minus six parenthesis plus five equals ten.
a) 3−1+4−3·(1−3) b) −5+8+3·[(5−4)·2−3·4]
c) 3+4 ·(2−5)−5:[5−2·(3−1)] d) 7·3−26: 2−3−5
