Insert parentheses to make each statement to make each statement true 6*7+2-1=53

The correct answer is 6 * (7 + 2) - 1 = 53. This is because in the Order of Operations, multiplying comes first. So to make sure you get the right answer, you have to put the 7 + 2 in parentheses to get 6 * 9 - 1 and not 6 * 7 + 1.
