Four and one that I carry are five, and eight make thirteen,and three sixteen; I write down six and carry one. One and one (that I carry) are two; I put down two.- The sum (or total, or the result of the addition) is two hundred and sixty. 37,80 and 143 added together, and(or make) 260. (2)Subtraction 减法 9-4=5 Nine minus four equals (or is equal to) five. 15-7=8 Seven from fifteen leaves eight. 23,654-8,175=15,479 8,175 (take or subtracted) from 23,654 leaves 15,479. The difference (or The remainder) is 15,479. Nine from five won`t go. 演算时的读法˖Nought from nought (leaves) nought. One from one leaves nought (or nothing). Two from three (leaves) one. I can`t take (or subtract) five from four; I must borrow ten; five from fourteen leaves nine.- The difference (or The remainder) is nine thousand one hundred. 5210 (take or substracted) from 14,310 leaves 9,100. (3)Multiplication 乘法 1×0=0 One multiplied by nought equals nought. 1×1=1 Once one is one. 2×1=2 Twice one is two. 3×5=15 Three times five is fifteen 6×0=0 Multiply six by nothing, and the result is nothing. 演算时的读法: Five times nine (or Nine multiplied by five) are forty-five; I put down five and carry four. Five times seven are thirty-five and four (that I carry) are thirty-nine; I write down nine and carry three. Five times six make thirty and three (that I carry) thirty-three; I put down thirty-three. Eight times nine (or Eight nine) are seven two; I write two and carry seven. Eight sevens make fifty-six and seven are sixty-three. I put down three and carry six. Eight sixes make forty-eight and six fifty-four; I write down fifty-four. I now add the partial results (or products) Five. Two and nine are eleven. Three and three are six and one are seven. Four and three make seven. Five. (4)Division 除法 9÷3=3 Nine divided by three maks (or is equal to) three. 20÷5=4 Five into twenty goes four times. 4567÷23=198 余 13 23 into 4567 goes 198 times, and 13 remainder. The quctient is 198, and 13 remainder. 演算时的读法: Fifteen into thirteen won`t go ; fifteen into one hundred and thirty-eight goes nine times; nine times fifteen are one hundred and threty-five; one hundred and thirty-five from one hundred and thirty-eight leaves three; I bring down seven; fifteen into thirty-seven goes twice; twice fifteen are thirty; thirty from thirty-seven leaves seven. The (exact) quotient is ninety-two, and seven remainder; 15 into 1387 goes 92 times, and 7 remainder. 5.Time 时间 (1)Hours 钟点 2h.5'8" = two hours five minutes eight seconds 2 小时 5 ߚ 8 秒 6.18 = six eighteen 6 时 18 ߚ 8.30 a.m.= eight thirty a.m.['ei 'em] Ϟ午 8 时 30 ߚ the 6.05 p.m.train = the six (nought) five p.m.['pi:'em] train ϟ午 6 时䳊 5 ߚ列车 又二十四小时混合制的写法和读法如ϟ˖ 0900 = 0 nine hunderd (Ϟ午)9 时 0910 = 0 nine ten (Ϟ午)9 时 10 ߚ 1300 = thirteen hundred 13 时(ϟ午 1 时) 1525 = fifteen twenty-five 15 时 25 ߚ(ϟ午 3 时 25 ߚ) 2000 = twenty hundred 20 时(ϟ午 8 时) at 5 o'c =at five o'clock Ѩ点钟 (2)Date 日期 Oct.1 =October first 10 ᳜ 1 日 Oct.1st = October the first 10 ᳜ 1 日 Ist Oct. 1949 = teh first of October, nineteen forty-nine 1949 ᑈ 10 ᳜ 1 日 3/5 = [英]May (the) third 5 ᳜ 3 日˗[美]March fifth 3 ᳜ 5 日 [附注]联系日期前置词用 on.
