That's the distributive property.
-30+15--9-6=
It is the additive identity property of zero.
Multiplying a 2-digit number by a 1-digit number involves multiplying the digits in the ones and tens place and then adding the products. Similarly, multiplying a 3-digit number by a 1-digit number follows the same principle, where you multiply the digits in the ones, tens, and hundreds place and then add the products. The main difference is that in the latter case, you are dealing with three sets of digits to multiply and add, whereas in the former, you only have two sets of digits.
They are different operations, giving different results. Example: 1+1=2, 1*1=1.
Double 31 is the result of multiplying 31 by 2, which equals 62. In mathematical terms, doubling a number means adding the number to itself. So, when you double 31, you are essentially adding 31 to itself, resulting in 62.
The answer is the distributive property
The distributive property of multiplication over addition.
The distributive property of multiplication over addition.
Multiplying a sum by a number gives the same result as multiplying each addend by the number and then adding the products together.
The property that states multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products is called the Distributive Property. It can be expressed mathematically as ( a(b + c) = ab + ac ), where ( a ) is the number being multiplied, and ( b ) and ( c ) are the addends. This property is fundamental in algebra and is used to simplify expressions and solve equations.
According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
The distrubutive property.... Multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. EXAMPLE: 3x(2+4)=18 (3x2) + (3x4) = 18
Distributive property
This is called the "distributive property" and has applications in algebra.
What Is Distributive Property? According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
The distributive property states that multiplying a sum by a number is the same as multiplying each addend by that number and then adding the products together. In other words, a*(b+c) = ab + ac. This property is fundamental in algebraic manipulations and simplifications.
The distributive property states that multiplying a sum by a number gives the same result as multiplying each addend by the number and then adding the products together.
