Nothing is a number, and no debt is a number

The number referred to by Nothing should be 5, because the pronunciation of Nothing and 5 is very similar, so it is more consistent with the overall meaning.

The effective use of numbers, as well as the use of simple techniques and quick calculations, can achieve accurate results for the overall result calculation.

Quick calculation of subtraction. One. Subtract two people from one complement subtraction.

The complementary subtraction of two digits minus one digit is: ten digits minus 1, and single digits plus complement. For example, 15 8 7, 15 minus 10 equals 5, 5 plus single digit 8 complement 2 equals 7.

Two. Multi-digit complement subtraction.

Complement subtraction is the method of subtracting 1 and supplementing, and subtracting two from three digits: 100 minus 1, 100 plus supplement, such as 268 89 179, the calculation procedure is 268 minus 100 is equal to 168, and 168 plus 89 complement 11 is equal to 179.

Three. Subtraction of reversed positions.

Two ten-digit numbers swap places, and there is a quick calculation method: ten digits minus a single digit, and then multiply by 9, which is the difference. For example, 86 68 18, the calculation procedure is 8 6 2, and 2 times 9 equals 18.

Four. Multi-digit subtraction.

Multi-digit subtraction, using the method of adding and subtracting complements to achieve quick calculation. First find the complement of the subtracted number, then add all the subtractions as additions, and then see what the complement of the sum is, and the complement of the sum is the difference sought.

For example: 653 35 67 43 168 340, first find the complement of the subtracted 653, the complement of 653 is 347, and then add and subtract 347 35 67 43 168 660, the complement of 660 is 340, and the difference is 340.

Multiplication quick calculation. One. Multiplication of two numbers up to 20.

Multiply two numbers within 20, add the single digit of one number and the other number and multiply it by 10, and then add the product of the two mantissa numbers, which is the number that should be obtained.

For example, 12 13 156, the calculation procedure is to add the mantissa 2 of 12 to 13, 13 plus 2 equals 15, 15 10 150, and then add the product of each mantissa to get 156, which is the product of the request.

Two. Multiplication of the head and tail complementary.

The two tens are multiplied, the first and last numbers are the same, and the last ten are complementary, and the calculation method is: the head plus 1, and then the head multiplies the front product, and the tail times the tail is the back product, and the two products are connected, which is the number that should be sought. Such as 26 24 624.

The calculation procedure is: the head of the multiplier 26 plus 1 is equal to 3, and then the head multiplied by the head, which is 3 2 6, the tail multiplied by the tail 6 4 24, connected to 624.
