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

**Ao quadrado** = squared

**Ao cubo** = cubed

Let me know if you have other expressions you would like to learn.
