We've picked up some easy tips, services, and apps. Being able to count in your head has many benefits throughout your life. 

By practicing calculations without a calculator, you :

Keep your brain toned. To work effectively, the intellect, like the muscles, needs constant training. Counting in the mind develops memory, logical thinking, and concentration increases the ability to learn, helps you navigate situations faster, and make the right decisions.

∙ Take care of your mental health. Studies show that counting verbally engages the parts of the brain responsible for depression and anxiety. The more active these areas are, the lower the risk of neuroses and black ennui.

∙ You are insured against punctures in everyday situations. The ability to quickly calculate change, tip size, calorie count, or interest

How to Learn to Add in Mind

Adding singe-digit numbers :

Start your practice at the elementary level by working with "Division worksheets" and adding single-digit numbers with passing the decimal point. This technique is mastered in first grade, but for some reason is often forgotten as you get older.

1.  Suppose you need to add 7 and 8.

2.  Count how many seven's are missing before ten : 10 - 7 = 3

3.  Decompose the eight into the sum of three and the second part : 8 = 3 + 5.

4.  Add the second part to ten : 10 + 5 = 15.

Adding up multi-digit numbers :

The basic principle is to divide the summable numbers into divisions (thousands, hundreds, tens, ones) and add the same numbers to each other, starting with the biggest ones.

Let's say you add 1,574 to 689.

1.  1,574 breaks down into four digits: 1,000, 500, 70, and 4. 689 is divided into three: 600, 80, and 9.

2.  Now add up: thousands with thousands (1,000 + 0 = 1,000), hundreds with hundreds (500 + 600 = 1,100), tens with tens (70 + 80 = 150), and ones with ones (4 + 9 = 13).

3.  Group the numbers as we see fit and add up what we get: (1,000 + 1,100) + (150 + 13) = 2,100 + 163 = 2,263.

The main difficulty is to keep all the intermediate results in mind. By practicing this kind of counting you also train your memory.

Multiplying single-digit numbers by multi-digit numbers :

Divide a multi-digit number into digits, multiply each digit by a single-digit number and sum up the results.

Let us use an example: 759 × 8.

1.  We divide 759 into digit parts: 700, 50 и 9.

2.  Multiply each digit separately: 700 × 8 = 5,600, 50 × 8 = 400, 9 × 8 = 72.

3.  Add up the results by each digit: 5 600 + 400 + 72 = 5 000 + (600 + 400) + 72 = 5 000 + 1 000 + 72 = 6 000 + 72 = 6 072.

Divide by a single-digit number : 

To do this, divide the original multi-digit number into manageable parts that are exactly divisible by our single-digit number.

Let's try dividing 2,436 by 7.

1.  Let's select the largest part from 2,436, which is evenly divisible by 7. In this case, it is 2 100. We obtain (2,100 + 336) / 7.

2.  We continue in the same way, but now with 336. It will divide 280 by 7. And the remainder will be 56.

3.  Now divide each part by 7: (2 100 + 280 + 56) / 7 = 300 + 40 + 8 = 348.

What will help you learn to count orally

Board games : 

Playing games that require you to constantly do mental arithmetic doesn't just mean you learn to count quickly. They combine doing useful things with having a good time with your family or friends.

Playing cards like Uno and all kinds of math dominoes allows schoolchildren to playfully learn simple addition, subtraction, multiplication, and division. More complex economic strategies, like Monopoly, develop financial acumen and sharpen complex numeracy skills.
