The seven elements often refer to the fundamental aspects of various concepts, such as the seven elements of art, which include line, shape, form, color, value, space, and texture. In a different context, the seven elements of a culture could include language, customs, beliefs, values, norms, material artifacts, and social institutions. Additionally, in the context of chemistry, one might refer to the seven diatomic molecules: hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. The specific "seven elements" can vary widely depending on the field of study.
rule method - writing a common property/a descriptive phrase, and agreeing that those objects, and only those are elments of the sets. ex. rule method X= X is an even number between 25 and 40. roster method X= {26,28,30,32,34,36,38}
7+7+7+7+7+7+7+7 is the same as 7 multiplied by 8, so the answer is 56.
7+7+7+7=28
One way (there may be more) is: 77/7 + 7 + 7 + 7 + 7/7 + 7/7 +7/7 + 7/7 + 7/7 = 11 + 21 + 5 = 37
7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 = 732 = 1104427674243920646305299201
