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.

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

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.
