Insert parentheses and/oraddition signs to make each equation true. Remember that parentheses can indicate multiplacation.
A. 3 2 4 1= 13
B. 3 2 4 1= 21
C. 3 2 4 1= 12
D. 3 2 4 1= 10
3+2(4+1) = 13
your turn ...
We’re Do you supposed to put the parentheses in 14 equals 50-42÷3+4×6
hey umm can someone help with this similar problem?
Insert operation signs and parentheses as needed to make the equation true.
4 3/4 _ 7 1/2 _ 1 1/6 _ 1 1/3 = 1
To make each equation true by adding parentheses and/or addition signs, we can consider the order of operations (PEMDAS/BODMAS). This means we need to perform arithmetic operations in Parentheses, then Exponents, then Multiplication and Division (from left to right), and finally Addition and Subtraction (from left to right).
A. 3 + 2 x 4 - 1 = 13
By applying the order of operations, we first multiply 2 and 4, then add the result to 3, and finally subtract 1.
B. (3 + 2) x 4 + 1 = 21
By adding parentheses around 3 + 2, we ensure that the addition is performed first. Then we multiply the sum by 4, and finally add 1.
C. 3 x (2 + 4) - 1 = 12
By adding parentheses around 2 + 4, we ensure that the addition is performed first. Then we multiply the sum by 3, and finally subtract 1.
D. 3 x 2 + 4 - 1 = 10
By applying the order of operations, we first multiply 3 and 2, then add the result to 4, and finally subtract 1.
Therefore, the answers with parentheses and/or addition signs are:
A. 3 + 2 x 4 - 1 = 13
B. (3 + 2) x 4 + 1 = 21
C. 3 x (2 + 4) - 1 = 12
D. 3 x 2 + 4 - 1 = 10
