.The
real-number system includes such numbers as –27,-2,2/3,… It is worthy of note
that positive numbers,1/2,1,for examples,are sometimes expressed as +(1/2),
+1.The plus sign,“+”,used here does not express the operation of addition,but
is rather part of the symbolism for the numbers themselves.Similarly,the
minus sign,“-“,used in expressing such numbers as -(1/2),-1,is part of thesymbolism for these numbers.

【这样翻译】:
“实数系统包括像-27,-2 ,2/3,……这样的数字.这里值得一提的是正数,例如:1/2,1,有时表示为:+(1/2),+1. 在这里,加号“+”通常不用写出,因为在符号表示法中这类数字本身就是正数.同理,在表示像-(1/2)、-1这样的数字时,就要用负号“-”了,这也是符号表示法要求的.
