2. How to translate a sentence in englishinto a equation in math Describe how to translate sentences in English intoequations in math. First youread the complete sentence to understandwhatequationitis in the wordproblem and thenyouwrite the math : Example 1 : Johnny workstwo times more than Alex Translation. j = 2xA Example 2 : Mary eat 3 apple more than Paul Translation. M = 3+P
3. Explainorder of operations Explain the order of operations. Why are they important? The order of operationsissome times referred to as pemdas. It stands for parenthesis,exponents,add,subtract,multiply,divide. Whenyou for examplesubtract or divide the order or operationis important to get the right result : Example 1: 15 – 9 = 6 (orderis important)
4. Perfect Square Whatis a perfect square number? A perfect square numberis an integermultipliedwithitselflike 5 x 5 = 25 : Example 1: the numbers 0, 1, 4, 9, 16, 25, 36 etc. are all perfect square numbers
5. Explainwhat a factor is. Whatis a GCF? A Gcfis an abrieviation of greatestcommon factor. The Gcfis the greatest factor out of the factorsyou are comparing. Factors are numbersthatcanbemultiplied by eachother to makeanothernumber. Somenumbers are prime factors,they con not besimplifiledbecausethere are no more factorsmakingthem. Exemple of Factors : the factors of 9 are : 1,3,9 The factors of 12 are : 1,2,3,4,6,,12 The factors of 15 are : 1,3,5,15
6. Describe real numbers Real numbers are basically all the numbersfrom rational to integers. Every single numberiscategorized as a real number. Exemple : Integers = 57,-32,15,-89 WholeNumbers = 1,12,44,76 Natural Numbers = 1,2,3,4 Rational Numbers = 0.5,0.25,0.70 Real numbers = 0.5,1232,-20,1/3
7. How to add and subtractintegers Describe how to add and subtractintegers. Whathappens if they are not the samesign ? Whenaddingintegerswith the samesignjustadd the twonumbers : Exemple : 4+5=9 or 30+60=90 Whenaddingintegerswithdifferentsignsthenfind the differencebetweenthem : Exemple : 10+-7=10-7=3 or 30+-20=30-20=10 If yousubtract a negativenumbersoitbecomes an addition : Exemple : 6--8=6+8=14 or 12--7=12+7= 19
8. Rules for multiplyingintegers Describe the rules for multiplying and dividingintegers. If you have a one negativenumber in the number sentence youwillalways have a negativeanswer : Exemple : 10x-8=-80 or 20x-15=-300 Exemple : 12/-8=-1.5 If you have twonegativesnumbers in the number sentence youwillalways have a positive answer : Exemple : -10x-8=80 or -20x-15=300 Exemple : -12/-8=1.5 If bothnumbers are positive then the answerwouldbe positive : Exemple : 10x8=80 or 20x15=300 Exemple :12/8=1.5
9. What are rootnumbers Explainwhat a root of a numberis. Whatis a square root? Cube root? How do wefindroot of numbers? The square root of a number X is the positive numberwhenmultiplyit by it self give X. Square root of 4 = 2 (2 x 2 = 4) Square root of 144 = 12 (12 x 12 = 144) Square root of 121 = 11 (11 x 11 = 121) The cube root of a number X is the positive numberwhenmultiplyit by it self 3 times gives X. Cube root of 8 = 2 (2 x 2 x 2 = 8) Cube root of 64 = 4 (4 x 4 x 4 = 264) Cube root of 125 = 5 (5 x 5 x 5 = 125)
