Computer classification 1, supercomputer, also known as supercomputer, it uses a large-scale parallel processing architecture, CPU by hundreds, thousands of processors, has a very strong computing capacity, mostly used in military, scientific research, meteorology, oil exploration and other fields



Which two types of calculators can be classified according to their functions?


① Arithmetical Calculator - can add, subtract, multiply, divide and other simple four operations, also known as simple calculator
② Scientific calculator, also known as function calculator, can calculate power, root, exponent, logarithm, trigonometric function, statistics, etc
③ Program Calculator - can be programmed to store more complex operation steps, repeated operations



The mathematics interest group held a test. There were 15 questions in the whole paper. It was stipulated that 8 points would be deducted for each right question and 4 points would be deducted for each wrong question. Xiaoying got 72 points in total, and she did it right______ Question


The wrong questions are: (8 × 15-72) △ 8 + 4, = (120-72) △ 12, = 48 △ 12, = 4 (DAO); he did right: 15-4 = 11 (DAO); a: he did right 11 questions. So the answer is: 11



The following four numbers are all natural numbers, where n is any natural number, the number s is equal to 0, and the number that must have factors 2 and 3 at the same time is ()
A. NNNSNNB. NSSNSNC. NSNSNSD. NSSNSS


A. N + N + N + S + N + n = 5N + s, because n is any natural number, so this number does not necessarily have a factor 2, 5N + s is not necessarily a multiple of 3, so this number does not necessarily have a factor 3, not in line with the meaning of the problem; B, N + S + S + N + S + n = 3N + 3S, because n is any natural number, so this number does not necessarily have a factor 2, 3N + 3S must be 3



Party A, Party B and Party C play the game of stone, scissors and cloth

Let the stone scissors be ABC respectively, then the event a, B and C can be AAA, AAB, AAC, ABA, abb, ABC, ACA, ACB, ACC, baa, bab, BAC, BBA, BBB, BBC, BCA, BCB, BCC, CAA, cab, cab, CBA, CBB, CBC, CCA, CCB, CCC respectively



There is a rectangular sheet of iron 40 cm in length and 20 cm in width. Please use it to make a 5 cm deep rectangular sheet iron box without cover (welding joints are ignored). How many welding methods do you have? What is the maximum volume of the tin box you made?


As shown in the figure: (1) (40-5 × 2) × (20-5 × 2) × 5 = 30 × 10 × 5 = 1500 (ML); (2) (40-5) × (20-5 × 2) × 5 = 35 × 10 × 5 = 1750 (ML); (3) (40-5 × 4) × 20 × 5 = 20 × 20 × 5 = 2000 (ML); answer: there are three welding methods, and the maximum volume of the tin box is 2000 ml
