# Integers: Mixed Operations -12 to 12

This packet helps students practice adding, subtracting, multiplying, and dividing with positive and negative numbers (a skill that is essential for algebra and is very often challenging for students!). This worksheet focuses just on numbers between -12 and 12, so students do not have to do long or complicated computation problems; they just need to accurately add, subtract, multiply, and divide integers. We consider these pages to be drills. We push students to finish them quickly, and make them repeat worksheets until they can do them with 100% accuracy. We find that the vast majority of mistakes that even high school students make in algebra stem from problem computation with integers. These "Mixed Operations" drills are the best test of whether students have mastered how to solve each type of integer problem.

*Find the solution.*

-12 + 7 =

-8 - 1=

-4 x -12=

-72 ÷ 9=

We encourage all students to have a full understanding of how negative numbers work before attempting these drills. We also encourage all students entering algebra to be able to complete these drills with 100% accuracy, in less than 5 minutes per page.
