When you hear the word "operations", you might think of a hospital procedure, but in math, the word "operations" refers to the four basic processes in math: add, subtract, multiply, and divide. Join us in this video as we practice our fluency in the first 3 operations: addition, subtraction, and multiplication. We'll practice the basic algorithm or steps, and also show you some other ways to think about and work with the numbers!
