Hi foreros!

I'm translating a question on a math test and I'm having trouble with the answers. Here is the question:

• What is the meaning of the following expression?
8 – n
A. A number increased by 8
B. A number decreased by 8
C. A number subtracted from 8
D. Eight subtracted from a number

In a previous thread the "# increased by" was talked about but the problem comes when I get to the last option:

¿Qué significa la siguiente expresión?

A. Un número más 8
B. Un número menos 8
C. Ocho menos un número
D. Eight subtracted from a number

My problem with translating it as más/menos is that it literally means a number plus 8, which gives the students a hint. In English the fact that it's written as "a number decreased by 8" is to challenge this students. Any ideas?

I see what you mean about the hint. Maybe you could say incrementado and reducido. Option D. could be Ocho restado a un número. B. and D are the same, aren´t they?

En matemáticas llamamos a la operación "+" suma o adición.
A la operación "-" resta o sustracción (también substracción aunque cada vez menos habitual)
A la operación "x" multiplicación o producto.
A la operación "/" división o cociente.
Esta información pretende servir para furturas referencias.

En respuesta a tu pregunta, yo diría "Ocho restado de un número" o "Un número menos ocho".

Utilizamos incrementar y decrementar de la siguiente manera:
"Un número decrementado ocho unidades" (n-8)
"Un número incrementado ocho unidades" (n+8)
