With tight deadlines, I understand math can be overwhelming, but panic does not have to be an option. Incorporating simple tricks to ease calculations solves a multitude of problems.
Here are 10 techniques designed for quick solution finding in math problems involving multiplication, division, and square roots. Covering a wide range of basic math functions, these tricks also aid in division, multiplication, square root extraction, and more.
- Subtract the Leading Digit
Elevating metrics math skills and streamlining mental math for complex calculations is possible by employing certain tricks. The best part is that these ways are so simple, kids and older pupils can easily apply them.
Psychology suggests demonstrating multiplication in halves greatly reduces math anxiety. For example, if one takes any odd number and multiplies it by five, the answer will always end in five. Ergo 6 \10 14 gives 4. Easy, right?
The strategy of rounding off or down any digit greater than two – that subtracts a hundred solves the case of gradual number depletion.
- Remove the second figure
Students with difficulties in two-digit subtraction are likely to benefit from this simple trick. This involves dividing numbers into their tens and ones places and then subtracting the ones place digit from its respective tens place. For instance, 7 – 5 becomes much easier to comprehend as 2.
Student trying to calculate a tip at a restaurant may find this trick particularly useful. It makes things much simpler for them time-wise as well as mental math-wise.
- Remove the third figure
Addition is challenging even for someone who is naturally quick with numbers, and so it is best tackled in small parts, for example, 83 + 29 can be simplified to 1 + 8 + 5 = 35.
Another way to become more efficient at addition is to quickly round off numbers, making it easy to add large sums in your head. This especially works well when used with multiples of ten, like 36 10 = 360.
- Remove the fourth digit
In the process of learning subtraction, it is important to understand the decomposition of numbers into manageable units for enhanced speed and precision. In this way, you can subtract and still be correct.
For some learners, subtraction can be one of the most frightening concepts to master, so here are some tips and strategies that can help make things easier.
Write the numbers you want to subtract from in order of their place value as – ones, tens, hundreds, and thousands, and begin subtracting numbers from each column until all have been subtracted from each one of them and the difference is written underneath.
- Remove the fifth digit
An important area of study for students is Mathematics and performing calculations in the head is often the most difficult. In any case, a number of strategies exist that make it easier to complete tasks more efficiently and less accurately.
One of the most effortless ways to multiply is to first divide the number by two, and then double the result. Take for example multipliying 5 with 8, divide 5 by 2 to get 8.
Working in tens can help simplify some subtraction tasks. Another simple way of subtracting decimals in within whole numbers is adding zeros to the end of each number.
- Take away the sixth digit Subtraction can be practiced by learners in hundreds charts. For example, in the case of 57-29, students need to look for 53 on the chart first and then subtract 2 tens and 9 ones from that.
Easily multiplied numbers can be multiplied in your head as for how to find 10 percent of a two-digit number quickly and easily do it by moving the decimal point of that number one place to the left. There are many other techniques in mental mathematics so make sure to learn them.
- Take away the seventh digit Removing the 7th digit from the given figure is simpler hence makes subtraction easier and to some degree enhances accuracy and speed of getting the answer.
The process of multiplying odd numbers can be relatively tricky, though there are tricks that can help. For example, in the case of 7 multiplied by 5, you could take 1 away from 5 resulting in 3 which gives you 3.
By using these techniques and strategies, you can improve your speed in calculations. Over time, mental mathematics will become less and less frightening.
- Take away the eighth digit It is always difficult to make subtraction when working with fractions or decimals but with practice, you will learn to calculate quicker and easier.
In the event that you are unsure of a number’s divisibility by nine, sum its digits to check. If they add up to a number that ends in this sequence (0, 2, 5, 9), then the number is most likely divisible by nine.
Rounding up or down large numbers makes calculations easier and quicker. Having rounded numbers makes it easier to calculate faster. These tips and tricks, when mastered, can greatly increase your calculation speed. If you stick to them, your results will amaze you!
- Remove the ninth digit
These techniques can help increase time accuracy in subtraction problems, as well as improve other areas of learning. These quick strategies will save time when performing calculations, while also promoting accuracy.
For subtraction, the first step is to find the answer for the nearest multiple of 10 to the number you are using, then add these multiples until you reach the needed answer.
While adding two numbers, eliminate pairs of digits from both the minuend and the subtrahend that total 9. Add all remaining digits until you have a single digit addend. Subtract that digit from the sum to get the answer.
- Remove the tenth digit.
Whether it is for a tip at a restaurant or for solving a difficult math problem in class, these easy strategies can aid in performing calculations easily while improving confidence and abilities at the same time.
One of the simplest tricks of mental math is to work with a base of 10. For example, when computing 36×5, multiply by 10, divide by 2 and the answer is 180. With this technique, addition and subtraction is much easier!
