Hi there, I'm wondering how to say general math operations in spanish.

For example,

two plus two is four
eight minus ten is negative-two
ten times eighteen is one hundred eighty
eighteen divided by ten is one-point-eight, or nine fifths.

this is my guess:
dos más dos es cuatro
ocho menos diez es... (i have no idea how to say negative)
and as for multiplication and division, i just don't have a clue

also, if you have any more complicated math operations in spanish that you know how to do, i'd love to hear about them.

Spanish, Colombia
dos mas dos es cuatro

ocho menos diez es menos dos

diez por dieciocho es ciento ochenta

dieciocho dividido por diez es uno punto ocho ó nueve quintos
dieciocho entre diez es uno punto ocho ó nueve quintos

Español (México)
You are right with the first ones.

dos más dos es cuatro
ocho menos diez es... usually we say menos dos (-2) for the result.
ten times eighteen is one hundred eighty diez por dieciocho o diez veces dieciocho (although this last one sounds a little old-fashioned)

eighteen divided by ten is one-point-eight, or nine fifths.
ocho entre diez or ocho didvidido entre diez.

8 When it is represented this way we usually say ocho sobre diez.
10

Mexico / Español
dos más dos igual a cuatro

ocho menos diez igual a... menos dos

diez veces dieciocho igual a ciento ochenta
(if it is a multiplication we say "diez por dieciocho igual a ciento ochenta"

dieciocho entre diez igual a uno punto ocho

You can also change "igual a" for "son/es"

In this thread (post number two) you'll find the names in spanish for the four basic math operations.

Hope it helps.

Hello Andréstable.

Negative numbers are said this way: "menos uno, menos dos,..."
Multiplication: "dos por tres son seis"
Division: "ocho entre cuatro son dos", or "ocho partido por cuatro son dos"

What other operations do you want to learn in Spanish?

muchísimas gracias! does anyone know any more complicated math terminology? for example,

10^2, or 8^4. (ten to the 2nd [10 squared] or 8 to the fourth). Is there a term like "squared" for ^2 or "cubed" for ^3?

what about "the square root of 3"?
or "log of 12"
how would you say this math sentence:

y=12x^2 + 5x

Spanish, Colombia
10^2 diez al cuadrado or diez a la dos ( I'd prefer the first one)
10^3 diez al cubo or diez a la tres ( I'd prefer the first one)
If the exponent is greater than three, i'd say
8^4 ocho a la cuatro
8^5 ocho a la cinco

log of 12= logaritmo en base diez de doce
ln of 12= logaritmo natural de doce

y=12x^2 + 5x = ye es igual a doce equis al cuadrado mas cinco equis.

I hope this helps you

8^4 ocho a la cuarta potencia
^3 al cubo

y=12x^2 + 5x

y igual a doce por x al cuadrado más 5 por x

wow, i didn't expect such an in depth reply. thanks a lot. i'm going to write that down in my calculus book and use it in class. lol. the teacher is my cousin. it's a blast. we're both huge nerds, my favorite class.

si, 10 ^ 2 se dice: 10 al cuadrado o 10 elevado a 2 y 10^3 se dice 10 al cubo o 10 elevado a la 3 o simplemente : diez a la 3.

The square root of 3 it would be: la raíz cuadrada de 3

The last one i did not understand

Was it what you wanted? Bye

F**k! he escrito demasiado lento! XD

13. ### AndréstableBanned

yes, thanks!

this one is kinda out there, but what about the cube root?

would it be "la raíz cuba de x" for "cbrt(x)"?

and this one may be even more out there...

sin(x), cos(x), tan(x), csc(x), sec(x), cot(x)?
how to write it would be beautiful, but if you knew how to pronounce it, i'd love you. and actually, i'm kinda betting that it's written the same.

I don't remember I should get back to secondary school

well i just tried the dictionary here and got all the same, additionally "secante" but nothing for cosecant or cotangent. but it probably just follows a pattern the others do, "cosecante" and "cotangente"

once again, thanks. and if anybody has any other random math-related terminology or math stuff they want to add, i'm on the edge of my seat here.

Hi,
csc(x)= cosecante
cot(x)= cotangente
sec(x)= secante

I believe in spain its said "uno coma ocho" instead of "uno punto ocho", since we use commas to separate decimals and dots for thousands.

Here are some other terms:

x^y : equis a la ye, or , equis a la y-esima potencia

polinomio : polinomial , grado: degre =degre(POL)

The hiperbolic functions:

sinh(x)=senh(x) : senohiperbólico de x
cosh(x)=cosh(x) : cosenohiperbólico de x
tanh(x)=tanh(x)=tgh(x) : tangentehiperbólica de x
sech(x)=sech(x) : secantehiperbólica de x
csch(x) : cosecantehiperbólica de x
ctanh(x)=ctgh(x) : cotangentehiperbólica de x

x! = factorial (english) : factorial (spanish) , is the same

En Argentina:

la división es: x dividido y
la multiplicación es: x por y
la potenciación es: x^y "x" elevado a la "y"...
y se usa: x al cuadrado, al cubo, a la cuarta, quinta, sexta, séptima, octava, novena.
Al menos en Argentina, el uso para la potencia 10 o mayores se dice: a la 10, a la 11, a la 12, etc en lugar de usar el ordinal (décima, undécima, etc)
es más fácil.

Por ejemplo (recordando la Universidad): el número de Avogadro 6,023 x 10^23 se lee: seis coma veintitrés por diez a la veintitrés.

Fracciones:
1/2 un medio, 1/3 un tercio, 1/4 un cuarto, 1/5 un quinto, un sexto, un séptimo, un octavo, un noveno, un décimo, un onceAVO, un doceAVO...
un noventa y nueve avo, un centésimo (1/100), un cientounavo (1/101), un novecientos noventa y nueve avo, un milésimo (1/1000)

PD: fact(ó)rial in english, factori(á)l in spanish
