45+70+152=267 45,70 and 152 added are (or make) 267

the sum (or total) is 267.

演算时的读法： Three and seven are ten; I write(or I write down,or I put down)a nought

and carry one. 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.
