The 444=6 algorithm holds under the following conditions:

1, with reverse thinking, 6=2+2+2, 2=√4, so the first algorithm is √ 4+√ 4 = 2+2 = 6.

2,6 is also equal to 2 times 2 plus 2, that is, 4 plus 2, so the second algorithm is √4×√4+√4=6, and additive commutative law is used to get √4+√4×√4=6. Additive commutative law is the addition of two numbers, and the order is reversed, and the final result remains unchanged.

Commutative law is a property of binary operation, which means that in an expression containing more than two commutative operators, as long as the operators have not changed, the order of their operations will not affect the calculated value.

Extended data:

Intelligence problem is a kind of ability problem. The topic can examine the respondent's attention, observation, logical thinking, imagination and memory in any form.

Four operations refer to four operations: addition, subtraction, multiplication and division. Four operations are the important content of primary school mathematics and the basis of learning other related knowledge.

Addition: the operation of combining two numbers into one number.

Subtraction: the operation of finding the other Jm number when the sum of two addends is known.

Multiplication: the operation of finding the product of two numbers.

Division: the operation of finding another factor by knowing the product of two factors and one of them.
