Today we are going to translate for Portuguese the basic calculations in Mathematics .

Watch the following infographic .

Let’s make it easier and see how to call the signs for each mathematical operation:

Sum sign = sinal de soma or sinal de mais (+)

Minus sign = sinal de menos (-)

Multiplying sign = sinal de multiplicar (x)

Divide sign = sinal de dividir (:)

Equal sign = sinal de igual (=)

When we are making a calculation , for example 4+1=5, in words we say “quatro mais um é igual a cinco”.

Let’s apply the same logic but for subtraction: 4-1=3 (quatro menos um é igual a três ).

To multiply 4×1=4 we say “quatro vezes um é igual a quatro”.

Finally , to divide we use the expression “a dividir por”. 4:2=2 ( quatro a dividir por dois é igual a dois).

There are other useful expressions . For example , the expression “do the maths” in Portuguese is “fazer as contas”( to calculate and reach a result of a mathematical operation).

We can be more specific and say something like:

a) fazer uma conta de somar (to do a sum operation)

b) fazer uma conta de subtrair ( to do a minus operation)

c) fazer uma conta de multiplicar ( to multiply)

d) fazer uma conta de dividir ( to divide).

Let’s have a look in other mathematical expressions:

raiz quadrada de = square root of

por cento = per cent
