Where do u place the grouping symbols to make this true? 3×5-8+7-3÷6=13
Put the markings around 8+7-3
hint: 15-2 = 13
To place the grouping symbols in the given expression to make it true, we need to carefully apply the order of operations (PEMDAS/BODMAS). Let's break it down step by step:
1. First, we focus on any operations inside parentheses. However, in this case, we don't have any parentheses in the given expression.
2. Next, we look for any exponents (powers), but again, there are none in this expression.
3. Moving on to multiplication and division from left to right, we see that the expression contains multiplication before division. Therefore, we need to perform the multiplication and division operations in the given expression.
The expression after performing multiplication and division becomes:
3 × 5 - 8 + 7 - (3 ÷ 6) = 15 - 8 + 7 - 0.5
4. Now, we proceed with addition and subtraction from left to right. So, we perform these operations one by one:
15 - 8 + 7 - 0.5 = 7 + 7 - 0.5 = 14 - 0.5 = 13.5
Based on the original expression, the result is 13, not 13.5 as we calculated. Thus, it is not possible to place grouping symbols to make the expression true.
