Solving aritmetic operation of integers with real life problems is the basis of the animation.
Integers can be solved through a number line, where addition and subtraction operation can be plotted on a number line and the results obtained.
Addition of integers follows: Closure property, Commutative law, Associative law, Additive identity and Additive inverse. For example, when integers have different signs, the sum will have the sign of the integer with the largest absolute value.
(+8) +( -4) = +4
(-8) + (+4) = -4
When subtracting integers, change the sign on the integer that is to be subtracted or the additive inverse can be used. The additive inverse of +7 is -7 (-7 + 7 = 0).
(+7) - (-4) = (+7) + (+4) = +11
(+7) - (+4) = (+7) + (-4) = +3
Multiplication is the repeated addition of integers. If the signs are the same, the product of integers will be positive, if they are different, the product of integers will be negative.
3 x 5 = 3+3+3+3+3 = 15
3 x 5 = 15
-3 x 5 = -15
-3 x -5 = 15
In division, if the signs are the same the quotient of integers will be positive, if they are different, the quotient of integers will be negative.
4 ÷ 2 = 2
4 ÷ -2 = -2
The simplification of integers section involves the use of BODMAS
4 + 8 x 12 -25 = 4 + 96 -25 = 100 - 25 = 75
There is a quiz on word problems in integers with detailed solutions that will give a thorough understanding of the concept.
The animation covers the arithmetic operations of solving integers using real life examples; a quiz section with detailed solution also checks your understanding.
