I cannot answer your question without a specific equation or problem to solve. Please provide me with the missing number problem and I will be happy to help you find the missing number and explain the property used.
If you are asking me to provide general information about filling in missing numbers, I can do that. Here are some common properties used to fill in missing numbers:
Commutative property of addition: This property states that the order in which we add numbers does not change the sum. For example, 3 + 4 = 4 + 3.
Associative property of addition: This property states that the way we group numbers when adding does not change the sum. For example, (3 + 4) + 5 = 3 + (4 + 5).
Commutative property of multiplication: This property states that the order in which we multiply numbers does not change the product. For example, 3 × 4 = 4 × 3.
Associative property of multiplication: This property states that the way we group numbers when multiplying does not change the product. For example, (3 × 4) × 5 = 3 × (4 × 5).
Identity property of addition: This property states that adding 0 to a number does not change the number. For example, 3 + 0 = 3.
Identity property of multiplication: This property states that multiplying a number by 1 does not change the number. For example, 3 × 1 = 3.
Inverse property of addition: This property states that for every number, there is an additive inverse that, when added to the number, gives the additive identity (0). For example, the additive inverse of 3 is -3, because 3 + (-3) = 0.
Inverse property of multiplication: This property states that for every number except 0, there is a multiplicative inverse that, when multiplied by the number, gives the multiplicative identity (1). For example, the multiplicative inverse of 3 is 1/3, because 3 × (1/3) = 1.
Property of zero for multiplication: This property states that any number multiplied by 0 is equal to 0. For example, 3 × 0 = 0.
I hope this information is helpful. Please let me know if you have any other questions.
