Learn the 30 Times Table
The 30 times table is easier to calculate when you connect it to multiplication by 3: multiply by 3, then make the result ten times as large.
Learn the multiplication table of 30 from 30 × 1 to 30 × 12, explore its connection with multiples of 3, and use the same method for larger calculations involving 30.
First calculate 3 × 7 = 21. Then make 21 ten times as large: 21 × 10 = 210.

Start With the 3 Times Table
Since 30 = 3 × 10, you can solve a multiplication by 30 in two stages. Find the corresponding ×3 fact first, then multiply that product by 10.
This means that knowing the 3 times table gives you the main multiplication fact you need. The final ×10 step changes the place value of the result.
Compare Multiples of 3 and Multiples of 30
For the same second factor, the product in the 30 times table is exactly ten times the corresponding product in the 3 times table.
Six groups of 3 give 18.
Six groups of 30 give 180, which is ten times 18.
3 × 11 = 33, so 30 × 11 = 330. The second result is ten times the first.
Follow the Sequence From 30 to 360
Each step in the 30 times table adds another group of 30. Knowing the sequence can help you move from a fact you remember to one beside it.
From 30 × 6 = 180, add 30 to reach 30 × 7 = 210. From 30 × 10 = 300, subtract 30 to find 30 × 9 = 270.
Multiples of 30 Are Multiples of Both 3 and 10
Because 30 = 3 × 10, every whole-number multiple of 30 has properties inherited from both factors.
90, 150, 210 and 360 all have 0 in the ones place.
For 210, the digits give 2 + 1 + 0 = 3.
A whole number is divisible by 30 exactly when it is divisible by both 3 and 10. So a ×30 product must end in 0 and its digit sum must be divisible by 3.
Use the 30 Times Table With Half-Hour Periods
One particularly useful way to meet multiples of 30 outside a multiplication exercise is through time. 30 minutes is half an hour, so repeated half-hour periods create multiples of 30 minutes.
120 minutes is the same duration as 2 hours.
180 minutes is the same duration as 3 hours.
This gives the sequence 30 min, 1 h, 1 h 30 min, 2 h, 2 h 30 min, 3 h as the number of half-hour periods increases.
Multiply by 10 First, Then Triple
You can perform the two steps in the opposite order. Start with the 10 times table and then make that result three times as large.
You do not need to use both methods every time. The important idea is that multiplication by 30 can be built from familiar operations instead of treated as an entirely separate set of facts.
Multiply Numbers Beyond 12 by 30
Once the ×3 then ×10 method makes sense, it can be applied to calculations far beyond the standard multiplication table.
Therefore, 30 × 24 = 720. Instead of memorizing this product, you can derive it from a simpler multiplication and a place-value step.
Practice Your Multiplication Skills
Mixed questions help you decide which known multiplication fact to use instead of simply continuing a memorized sequence.

30 Times Table Questions
Review the main ×30 products, sequence and mental-math method.
What is the 30 times table?
From 30 × 1 to 30 × 12, the products are 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330 and 360.
What is 30 × 5?
30 × 5 = 150.
What is 30 × 6?
30 × 6 = 180.
What is 30 × 7?
30 × 7 = 210. Since 3 × 7 = 21, multiply 21 by 10.
What is 30 × 8?
30 × 8 = 240.
What is 30 × 9?
30 × 9 = 270.
What is 30 × 10?
30 × 10 = 300.
What is 30 × 11?
30 × 11 = 330.
What is 30 × 12?
30 × 12 = 360.
What is the easiest way to multiply by 30?
Multiply the other factor by 3 and then multiply that result by 10. For example, 30 × 8 becomes 3 × 8 = 24, followed by 24 × 10 = 240.
What are the first 12 multiples of 30?
The first 12 positive multiples of 30 are 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330 and 360.
How are multiples of 30 connected to time?
Thirty minutes is half an hour, so repeated 30-minute periods create familiar time intervals. For example, 30 × 4 = 120 minutes, which is 2 hours, and 30 × 6 = 180 minutes, which is 3 hours.
