Math games for grade 12345 can be simple when your little one knows these fabulous 4 math tricks. Try these out and see the difference.
Adding Large Numbers
When you have to add large numbers, you can try making the numbers a multiple of 10. For example, if you have to add 25 and 36, you can try adding 30 with 40. The result becomes 70. Now, subtract the numbers you have added. 30-25 is 5 and 40-36 is 4. The sum of 5 and 4 is 9. You need to subtract it from the previous result. So, the result will be 70-9=61.
Subtracting from 1000
When you have to subtract a digit from 1000, the best trick is to subtract the last number from 10 and the previous numbers from 9. For example, if you have to subtract 387 from 1000, here is what you have to do. 9-3=6, 9-8=1, 10-7=3. So, the result is 613.
Multiplying Anything with 5
To multiply an even number with 5, cut the number in half and add a zero to it. For example, if you multiply 4 with 5, half of 4 is 2 and adding a zero to 2 makes it 20. The result is 20. To multiply an odd number with 5, subtract 1 from the number, halve the number and add a 5. For example, if you multiply 3 with 5, subtracting 1 from 3 makes it 2, halving 2 makes it 1, and adding a 5 after 1 makes it 15, which is the result.
Here are some dividing tricks that you can learn and keep in mind. Math games for grade 12345 will be easier to solve when you apply these tricks. You can easily know which numbers can be evenly divided by the following numbers.
- 2 if the number ends in 8,6,4 and 2.
- 3 if the addition of the numbers is evenly divisible by 3.
- 4 if the number ends in 00 or if the addition is evenly divisible by 4.
- 5 if the number ends in 5 or 0.
- 6 if it’s an even number and the addition of the numbers is evenly divisible by 3.
- 10 if the number ends in 0.
