What is 70 x 5? The Simple Answer
If you are wondering about 70 x 5, you’re asking for the result of multiplying the number 70 by 5. The answer is straightforward:
70 x 5 = 350
Multiplication might seem elementary, but it’s the backbone of countless real-world applications, from quick mental math at the grocery store to solving complex math problems on scientific calculators. Let’s take a closer look at what this calculation means, how you can approach it, and why mastering these basics can offer so much value.
Breaking Down the Multiplication: How to Approach 70 x 5
Multiplication isn’t just about finding the answer; it’s about understanding the process. Here’s how to break down 70 x 5 step-by-step:
1. Understanding Place Value
- 70 consists of two digits: 7 in the tens place (which means 7 x 10) and 0 in the ones place.
- 5 is a single-digit number.
2. Simple Multiplication Steps
Method 1: Multiply Directly
- Stack 70 and 5:
70
x 5
—-
-
Multiply 5 by 0 (the ones place of 70):
5 x 0 = 0 -
Multiply 5 by 7 (the tens place of 70):
5 x 7 = 35 -
Since the 7 was in the tens place, add a zero:
35 x 10 = 350
Method 2: Using Distributive Property
Break 70 down as (7 x 10).
- 70 x 5 = (7 x 10) x 5
- Rearranged: 7 x (10 x 5)
- 10 x 5 = 50
- 7 x 50 = 350
Method 3: Repeated Addition
If you prefer, you can add 70 five times:
- 70 + 70 + 70 + 70 + 70 = 350
3. Using a Calculator
- Type in 70, press “×”, then 5, then “=”.
- You’ll see the result: 350
