Explain How do you determine the difference when subtracting two integers with different signs?
Examples: Write the first integer as it is, turn the subtraction into the addition, change the sign of the second integer, and follow the rules of addition. -7 - (2) = -7 + (-2) = -(7 + 2) = -9 10 - (-8) = 10 + (+8) = 18
Why change mixed numbers to improper fractions?
For addition, subtraction, division and multiplication with other fractions
What is the rule for subtracting integers?
if they are two positive numbers, do it normally.If there is a negative and a positive, change it to addition and switch the SECOND integer sign. Only works with two integers in a subtraction question.Example: (-32)-(+2)= (-34) / (-32)+(-2)=(-34)
What is different between constant and integer?
A constant is a value that does not change, an integer is a positive whole number.
What does it mean when your slope is an integer?
Nothing particularly. All that it means is that your measurement units for the variables are such that a unit change in the horizontal axis is accompanied by a change of a whole number of units for the other variable. A integer gradient for a variable against time, when the latter is measured in seconds will be 1/3600 of that gradient when the time is expressed in hours - quite possibly that will be a non-integer. So what?
How does an expression of addition change to subtraction?
Adding +k is the same as subtracting (-k).
In x - 3 does absolute value change the subtraction into addition?
no, the absolute value does not change the subtraction into addition. it does however, change the difference to positive ( if the difference is negative)
What are the rules in addition and subtraction integers?
The rules for addition are as follows:The sum of two negative integers is a negative integerThe sum of two positive integers is a positive integerThe rules for subtraction are as follows:If they are two positive numbers, do it normallyIf there is a negative and a positive ,change it to addition and switch the SECOND integer sign
Does addition and subtraction of vectors obey the commutative law?
Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.
Why are brackets sometimes used in an expression?
They may be used to denote a function. They are also used to change the order in which the operations of index (exponentiation), division or multiplication, addition or subtraction are carried out.

Why when subtracting a negative number must you change the subtraction sign to an addition sign?
Because a negative negative is the same a a positive, and because of the definition of subtraction and addition.

What is negative eight minus two?
Negative - a positive would make it keep it change it change it so the problem would look like this -8 + -2 = -6, Im in honors math just to let you know, with all the subtraction problems, if they are integers,you do keep it change it change it keep the first digit and don't do anything to it change the subtraction sign to an addition sign and if the next integer is positive make it a negative if it is a negative make it a positive.
What addition property do you use to change the order of an expression?
Commutativity and associativity.
How do you solve an equation involving subtraction of positive and negative numbers?
well it is easy to the second integer change the sigh to the opposite one and also change the subtraction sign to a adding sign and add ex 3- +5= 3+-5=-2
How do you change a subtraction problem into an addition?
make it a '+ negative number'. Example: 6 - 7 = -1 6 + (-7) = -1
