What is 17-17*17+17?

What is the answer to 17-17*17+17?

17-17*17+17 = -255

Whenever you are dealing with any mathematical operation just remember “PEDMAS” and proceed accordingly.

P - Parenthesis

E - Exponents

D - Division

M - Multiplication

A - Addition

S - Subtraction

Using PEDMAS means that the order to solve an arithmetic expression is Parenthesis → Exponents → Addition / Subtraction  → Multiplication / Division.

We want to solve this expression: 17-17*17+17"?

In this case we don't have neither parenthesis nor exponents. So, “PEDMAS” we get:

17 - 17 × 17 + 17 = ?

= 17 - 289 + 17 (multiplication)

= 17 -272 (addition)

= -255 (subtraction)

Thus,

17 - 17 × 17 + 17 = -255 (answer)

The most common mnemonics for remembering the order of operations are:

PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction

BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.

GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
