Zero times any number equals zero.
What’s next
Next, you'll use these foundational rules to master the multiplication facts for 0, 1, 2, and 5, building speed and accuracy.
In this Grade 4 lesson from Saxon Math Intermediate 4, students begin memorizing multiplication facts for the factors 0, 1, 2, and 5, learning key rules such as zero times any number equals zero, one times any number equals the number itself, two times any number doubles it, and multiples of 5 always end in zero or five. Students practice applying the Zero Property and Identity Property of multiplication while solving related problems and equations.

Section 2
Zero times any number
Zero times any number equals zero.
Think of multiplying as having groups of something. If you have 8 groups of 0 items, you have nothing! Zero has the superpower to make any number it multiplies disappear into, well, zero! It's the ultimate magic trick where the number vanishes every single time.
Section 3
One times any number
One times any number equals the number.
Multiplying by one is like a number looking in a mirror. It sees itself and stays exactly the same. One group of seven is just seven. That’s why it’s called the identity property, because the number always keeps its original identity! How cool is that?
Section 4
Two times any number
Two times any number doubles the number.
Multiplying by two is just a cool shortcut for doubling! You are simply adding the number to itself. So, is the same as . It’s like instantly creating a twin for any number you are working with. Twice the fun!
