How are addition and subtraction related?
They are inverses. For any numbers a, b, and c if: a + b = c then: a = c - b and b = c - a In words, addition is raising the value of a number by counting higher, (1, 2, 3, ...). Subtraction is the inverse (you count down 3, 2, 1, ...).
What is the fact families for 6 7 42?
6 * 7 = 42 7 * 6 = 42 42 / 6 = 7 42 / 7 = 6
What is the fact families for 7 9 63?
Well, isn't that just a happy little question! The fact families for 7, 9, and 63 are all related in a special way. You see, in this family, 7 x 9 = 63, 9 x 7 = 63, 63 ÷ 7 = 9, and 63 ÷ 9 = 7. Just like a family, each number has a special connection to the others.
Explain how the subtraction of integers is related to the addition of integers?
Subtraction of integers is essentially addition of integers except the second integer is inverted. For example: 5 + 3 = 8 is a simple addition of integers. 5 - 3 = 5 is a simple subtraction of integers. It can be expressed by inverting the second value (the one right after the subration sign) and then switching the subtraction sign to an addition sign. So it would look like: 5 + (-3) = 5. Note that (-3) is the opposite of 3. So to do a more confusing subtraction problem like: 55 - (-5), we could rewrite this as: 55 + -(-5). From here it's easy to see that the two negatives cancel out. 55 + 5 = 60.
What is the fact family of 8 5 40?
Well, darling, the fact family of 8, 5, and 40 consists of the numbers 8, 5, and their products and division results. So, in this case, the fact family would be 8 x 5 = 40, 5 x 8 = 40, 40 ÷ 8 = 5, and 40 ÷ 5 = 8. It's as simple as that, sugar.
How addition and subtraction related?
Addition and subtraction are reverse operations.
How are addition and subtraction of integers related?
Addition and subtraction are inverse functions.
What is a set of related addition-subtraction or multiplication-division sentences?
A set of related addition-subtraction or multiplication-division sentences is a fact family.
What is the fact family of 47?
A fact family consists of a set of related addition and subtraction or multiplication and division equations that use the same numbers. For the number 47, a simple fact family involving addition and subtraction could be: 20 + 27 = 47, 27 + 20 = 47, 47 - 20 = 27, and 47 - 27 = 20. This illustrates how the numbers 20, 27, and 47 relate to each other through these basic operations.

How is preparing taxes related to math?
You use numbers and add/subract them. You also work with your budget, which is using math. Income tax forms use addition, subtraction, multiplication, division, etc.
Is algebra arithmetic?
No, algebra is not arithmetic. While both algebra and arithmetic involve numbers and mathematical operations, algebra is a branch of mathematics that goes beyond the basic arithmetic operations (addition, subtraction, multiplication, and division) to include variables, equations, and abstract mathematical concepts.
