Several Useful Speed Math Tricks
If you wonder how to do mental math just look at these 6 easy tricks:
1. How to Add Large Numerals Quickly
If you need to add up such numerals as 473 and 658, it might seem challenging. But there is an easy way to do it. Rounding is the key. So the 473 will become 480 and 658 – 660.
Next, add 480 + 660 = 1140
But there is one more step – subtract the numbers that you’ve added before that.
So you’ve just added 7 to 480 and 2 to 658
This means that first, you add up 7 + 2 = 9. Now just subtract it from 1140.
1140  5 = 1131. Here, now you know it!
2. How to Subtract from 1,000
It is also much simpler than it seems! Follow these 3 simple steps and get your answer. If you need to subtract big numbers from 1,000, first subtract each one individually from 9, except the last numeral, because it has to be subtracted from 10. For instance:
1,000  189 = ?
9  1 = 8
9  8 = 1
10  9 = 1
The answer is 811.
3. How to Multiply Large Numbers
Multiplying by 10 is simple – just add 0 at the end of the original number. For instance:
267 x 10 = 2670
There is another related trick. How to multiply by 5 if the starting number is like 7,854? Just divide it by 2 and multiply by 10!
So it looks like that:
7,854 : 2 = 3,927
3,927 x 10 = 39,270
4. How to Figure Out Percentage
Lots of us struggle with this one, especially when we go to the restaurant and have to calculate tips. So here is another hack: just switch the percentage! How does it work? Do you need to figure out how much is 10% from, say, 60? Than switch like that – 60% from 10. Both results are equal 6.
5. How to Multiply Quickly
If you need to multiply twodigit number by onedigit number, then you should first multiply each of twodigits and then add them to get the result. Example:
57 x 7 = ?
50 x 7 = 350
7 x 7 = 49
350 + 49 = 399.
6. Multiplication of Numbers with Zero
This is also very easy. If you need two numbers that end with zero multiplied just multiply the other numbers together and add up all zeroes at the end. Example:
150 x 500 = ?
15 x 5 = 75
Now add three zeros to the end:
150 x 500 = 75,000
75, 000 is your result! Isn’t it simple?
Of course, there are much more of speed arithmetic hacks, and you can learn them to increase your skills in arithmetic. They all are quite effortless and logical, so memorizing them shouldn’t be a problem. And the next time at groceries, you will impress everyone.
