Hcf & lcmweerawattkThis document provides examples of calculating the highest common factor (HCF) and lowest common multiple (LCM) of various number sets. It gives the HCF of 12 and 32 (4), 18 and 45 (9), 12, 32, and 18 (2), and 18, 45, and 6 (3). It also lists the LCM of 12 and 32 (96), 18 and 45 (90), 12, 32, and 18 (288), and 18, 45, and 6 (180).
5ใบกิจกรรมhcf and lcmweerawattkThe document discusses the highest common factor (HCF) and lowest common multiple (LCM) of various number sets. It provides examples that the HCF of 24 and 36 is 12, the HCF of 42, 60 and 90 is 6, the LCM of 4, 12 and 24 is 24, and the LCM of 12 and 18 is 36.
Integers mult-div-2blpxvlweerawattk1) To determine if the answer to multiplying or dividing integers is positive or negative, use the mnemonic "Mr. Multiplivision".
2) If the factors have the same sign, the answer is positive. If the factors have different signs, the answer is negative.
3) Examples are provided to demonstrate multiplying and dividing integers, such as -30 / 3 = -10 and -13 * -6 = 78.
4ใบกิจกรรมmulti diviweerawattkThe document provides instructions on how to simplify mathematical expressions by writing them out in words. It contains 15 math problems for the reader to solve by using rules to write out the expressions verbally. The problems cover multiplication, division, positive and negative numbers. The reader is encouraged to use their brain's reasoning abilities to work through the step-by-step process.
Ordering whole numbersweerawattkWhole numbers can be compared using symbols such as greater than (>), greater than or equal to (≥), less than (<), less than or equal to (≤), and equal to (=). The symbol > means the number to the left is greater than the number to the right, ≥ means greater than or equal to, < means less than, ≤ means less than or equal to, and = means the two numbers are equal.
Addition and subtraction integersweerawattkThis document introduces addition and subtraction of integers. It explains that for addition, if the signs are the same you add the numbers and keep the sign, and if the signs are different you subtract the numbers and use the sign of the larger number. For subtraction, you change it to addition by making the subtrahend positive and follow the addition rule. Examples are provided to illustrate adding and subtracting integers using tiles or numbers. A rhyme is also presented to help remember the addition rule.
