1-1+1×1÷1
Using the order of operations (PEMDAS/BODMAS), we solve this expression step by step:
1-1+1×1÷1
= 0+1×1÷1
= 0+1÷1
= 0+1
= 1
Therefore, 1-1+1×1÷1 equals 1.
To evaluate the expression 1-1+1×1÷1, we need to follow a specific order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
Let's break it down step by step:
1. Start with multiplication and division:
There is only one multiplication and division operation in the expression, which is 1×1÷1. Since both multiplication and division have the same order of precedence, we evaluate it from left to right.
1×1 = 1
1÷1 = 1
The expression becomes 1-1+1.
2. Move on to addition and subtraction:
Both addition and subtraction have the same order of precedence, so we evaluate them from left to right.
1-1 = 0
0+1 = 1
The final answer to the expression 1-1+1×1÷1 is 1.
Therefore, the expression evaluates to 1.
To solve the expression 1-1+1×1÷1, we follow the order of operations, which is also known as the "PEMDAS" rule.
P: Parentheses (simplify expressions inside parentheses)
E: Exponents (perform any exponentiations)
MD: Multiplication and Division (perform multiplications and divisions from left to right)
AS: Addition and Subtraction (perform additions and subtractions from left to right)
Applying the order of operations to the given expression:
1 - 1 + 1 × 1 ÷ 1
Multiplication and Division take precedence over Addition and Subtraction, so we start with those operations:
1 × 1 = 1
1 ÷ 1 = 1
Now, the expression becomes:
1 - 1 + 1 ÷ 1
Next, we perform the additions and subtractions from left to right:
1 - 1 = 0
0 + 1 = 1
Therefore, 1-1+1×1÷1 equals 1.
