To evaluate mathematical expressions, follow the BODMAS (brackets, order, division/multiplication, addition/subtraction) rule.
6. Evaluate 4*4 - 14/2 + 6:
Step 1: Start by solving any calculations within parentheses or brackets. In this case, there are no parentheses or brackets.
Step 2: Next, calculate any divisions or multiplications from left to right.
Perform 14/2 = 7.
Step 3: Continue with any additions or subtractions from left to right.
Perform 4*4 = 16.
Perform 16 - 7 = 9.
Then, perform 9 + 6 = 15.
So, the evaluation of the expression 4*4 - 14/2 + 6 is 15.
7. Evaluate 2 * [1 + (19 + 13) / 4]:
Step 1: Start by solving any calculations within parentheses or brackets.
Perform 19 + 13 = 32.
Step 2: Perform any divisions or multiplications from left to right.
Perform 32 / 4 = 8.
Step 3: Continue with any additions or subtractions from left to right.
Perform 1 + 8 = 9.
Step 4: Multiply the result from Step 3 with the number outside the brackets.
Perform 2 * 9 = 18.
So, the evaluation of the expression 2 * [1 + (19 + 13) / 4] is 18.
8. Evaluate 50 + 25 / 5^2:
Step 1: Start by solving any calculations within parentheses or brackets. In this case, there are no parentheses or brackets.
Step 2: Perform any divisions or multiplications of powers (exponents) from left to right.
Perform 5^2 = 25.
Step 3: Perform any divisions or multiplications from left to right.
Perform 25 / 25 = 1.
Step 4: Perform any additions or subtractions from left to right.
Perform 50 + 1 = 51.
So, the evaluation of the expression 50 + 25 / 5^2 is 51.
