Why does minus and minus equal plus?
Because a minus changes the sign. If you take a plus and change it to a minus,you get a minus. If you take a minus and change it to a minus, it changes backinto a plus. Because you have only two options, minus and plus, here are all theoptions:+ & - = -+ & + = +- & + = -- & - = +===========================================Everything above the double line is a misleading, even dangerousdiscussion. When it's all over, both the questioner and the responderthink they have it all worked out, where in reality, it's all meaningless.The main problem is: Neither of them ever explains what ' and ' meansin the question, or what ' & ' means in the answer. Neither of those isa mathematical operation. The statement in the question, and the listof 4 'rules' in the answer, are correct for some mathematical operationsand either indeterminate or dead wrong for others.The question says: " ... minus and minus equal plus. "-- If ' and ' means multiplication or division, then it's a true statement.-- If ' and ' means subtraction, then it may or may not be true, dependingon the size of the two numbers.-- If ' and ' means addition, then it's always false.In the list of 4 items in the answer:-- If ' & ' means multiplication or division, then all 4 items are correct(but almost impossible to remember in this form).-- If ' & ' means addition, then items #1 and #3 are sometimes true andsometimes false, item #2 is always true, and item #4 is always false.-- If ' & ' means subtraction, then item #1 is always false, items #2 and #4are sometimes true and sometimes false, and item #3 is always true.
How do you make the numbers 11-20 using four 4's?
11 = (42 - 4) - (4 / 4) 12 = (4 + 4) + (√4 + √4) 13 = (42 - 4) + (4 / 4) 14 = (4 + 4 + 4 + √4) 15 = (4 * 4) - (4 / 4) 16 = (4 + 4 + 4 + 4) 17 = (42 + √4) - (4 / 4) 18 = (42 + 4) - (4 - √4) 19 = (42 + 4) - (4 / 4) 20 = (4 * 4) + (√4 + √4)
How do you make the numbers 1-10 with four 4's using BODMAS?
Here is one set of solutions. The answers here are not unique. 1 = (4*4)/(4*4) 2 = 4/4 + 4/4 3 = (4+4+4)/4 4 = (4-4)*4 + 4 5 = (4*4 + 4) / 4 6 = 4 + (4+4)/4 7 = 4 + 4 - 4/4 8 = 4 + 4 + 4 - 4 9 = 4 + 4 + 4/4 10 = (44 - 4)/4
How do you get 4 by using four 4's?
3 simple solutions (there are more): (4-4)/4 + 4 = 4 4*(4-4)+ 4 = 4 4-((4-4)/4)) = 4
How do you represent all of the integers from 0 to 100 by relating exactly four 4's together with mathematical symbols?
I'll start it, but I'm not going to finish it! 4 X 4 / 4 - 4 = 0 44 / 44 = 1 4 / 4 + 4 / 4 = 2 (4 + 4 + 4) / 4 = 3 (4 / 4)4 X 4 = 4 (4 / 4)4 + 4 = 5 (4 + 4) / 4 + 4 = 6 44 / 4 - 4 = 7 4 + 4 + 4 - 4 = 8 4 / 4 + 4 + 4 = 9 (44 - 4) / 4 = 10 (44 + 4) / 4 = 12 4! - 44 / 4 = 13 4! / 4 + 4 + 4 = 14 44 / 4 + 4 = 15 4 + 4 + 4 + 4 = 16 4 X 4 + 4 / 4 = 17 4 / √4 + 4 * 4 = 18 4! - 4 + 4 - 4 = 20 4! / 4 + 4 X 4 = 22 4 X 4 + 4 + 4 = 24 44 - 4 * 4 = 28 (4 + 4 / 4)! / 4 = 30 44 / (4 + 4) = 32 4! + 44 / 4 = 35 4! X 4! / 4 / 4 = 36 44 - 4 / √4 = 42 44 - 4 / 4 = 43 44(4/4) = 44 4 / 4 + 44 = 45 44 + 4 / √4 = 46 (4 + 4 + 4) X 4 = 48 √4 * 4 + 44 = 52 4 X 4 X 4 - 4 = 60 44 / 4 - √4 = 62 4(4 - 4/4) = 64 44 / 4 + √4 = 66 4 X 4 X 4 + 4 = 68 4! X 4! / (4 + 4) = 72 (4 X 4 + 4) X 4 = 80 (4 - 4 / 4)4 = 81 √4 * 44 - 4 = 84 √4 * 44 - √4 = 86 44 + 44 = 88 √4 * 44 + √4 = 90 √4 * 44 + 4 = 92 4! X 4 / 4 X 4 = 96

Do all numbers that end in a 4 are they multiples of 4?
No; for example, 14 ends with 4 but is not divisible by 4. One trick for determining if a large number is divisible by 4 is only look at the last 2 digits. If that number is divisible by 4, so is the entire number. For example, 147,328,120 is divisible by 4 because 20 is divisible by 4. But 483,394,399 is not because 99 is not divisible by 4.
