1 序數詞和基數詞是不同的，序數詞表示順序，基數詞表示數量。
2 因為序數詞是在數字後面加上字母th，表示第幾個，如：first（第一）、second（第二）；而基數詞則直接表示數字數量，如1（one）、99（ninety-nine）。
3 因此，答案是：序數詞：1st、2nd、3rd、4th、5th、6th、7th、8th、9th、10th、...99th基數詞：1、2、3、4、5、6、7、8、9、10、...99

關於這個問題，1-99的基數詞和序數詞如下：

基數詞：1-99（one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three, twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty, thirty-one, thirty-two, thirty-three, thirty-four, thirty-five, thirty-six, thirty-seven, thirty-eight, thirty-nine, forty, forty-one, forty-two, forty-three, forty-four, forty-five, forty-six, forty-seven, forty-eight, forty-nine, fifty, fifty-one, fifty-two, fifty-three, fifty-four, fifty-five, fifty-six, fifty-seven, fifty-eight, fifty-nine, sixty, sixty-one, sixty-two, sixty-three, sixty-four, sixty-five, sixty-six, sixty-seven, sixty-eight, sixty-nine, seventy, seventy-one, seventy-two, seventy-three, seventy-four, seventy-five, seventy-six, seventy-seven, seventy-eight, seventy-nine, eighty, eighty-one, eighty-two, eighty-three, eighty-four, eighty-five, eighty-six, eighty-seven, eighty-eight, eighty-nine, ninety, ninety-one, ninety-two, ninety-three, ninety-four, ninety-five, ninety-six, ninety-seven, ninety-eight, ninety-nine）

序數詞：1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, 19th, 20th, 21st, 22nd, 23rd, 24th, 25th, 26th, 27th, 28th, 29th, 30th, 31st, 32nd, 33rd, 34th, 35th, 36th, 37th, 38th, 39th, 40th, 41st, 42nd, 43rd, 44th, 45th, 46th, 47th, 48th, 49th, 50th, 51st, 52nd, 53rd, 54th, 55th, 56th, 57th, 58th, 59th, 60th, 61st, 62nd, 63rd, 64th, 65th, 66th, 67th, 68th, 69th, 70th, 71st, 72nd, 73rd, 74th, 75th, 76th, 77th, 78th, 79th, 80th, 81st, 82nd, 83rd, 84th, 85th, 86th, 87th, 88th, 89th, 90th, 91st, 92nd, 93rd, 94th, 95th, 96th, 97th, 98th, 99th

序數詞和基數詞的總個數為99+9=8個因為9分別對應了十個基數詞（9）和十個序數詞（t-9th），而-90每十個數中只有一個序數詞，其他都為基數詞；0-900每百個數中只有一個序數詞，其他都為基數詞
因此，99個數中有9個序數詞，其餘都為基數詞，加上九個只有基數詞的個位數，共計8個
序數詞和基數詞在英語語法中有著不同的用法和構造，因此，對於英語學習者來說，熟練掌握序數詞和基數詞的用法及其構造非常重要

序數詞和基數詞不相等，因為序數詞表示數量的順序或次序，而基數詞表示具體的數量或數值大小。
例如，1是基數詞，但是在“第一”中，1就是序數詞。
因此，1-99的序數詞和基數詞是不相等的。
在英語中，序數詞的寫法和基數詞的寫法通常不同。
例如，1在基數詞中寫作“one”，而在序數詞中寫作“first”。
在使用時，需要根據具體的語境和要求來選擇使用哪種表達方式。
