Arrange the expressions below in order from least to greatest. Place the least at the top and greatest at the bottom.
(72÷8)−2×3+1
72÷(8−2)×3+1
72÷(8−2)×(3+1)
72÷8−2×(3+1)
72÷8−2×(3+1) < (72÷8)−2×3+1 < 72÷(8−2)×3+1 < 72÷(8−2)×(3+1)
Simplified:
9 - 8 < 7 < 54 < 18
can you do it from top to bottom with the least being at the top and the greatest being at the bottom?
Sure! Here are the expressions arranged from least to greatest:
(72÷8)−2×3+1
72÷(8−2)×3+1
72÷(8−2)×(3+1)
72÷8−2×(3+1)

3 = 19
(7 ÷ 4) + 5 × 3 = 19
can you use the numbers but add math symbols and use pemdas?
Sure! Here's one possible solution using PEMDAS:
12 ÷ (7 - 4) + 5 × 3 = 4 + 15 = 19
Note that we first perform the subtraction inside the parentheses (7 - 4), then the division (12 ÷ 3), then the multiplication (5 × 3), and finally the addition (4 + 15) from left to right to get the result of 19.

A. 8 × (30 + 5) = 8 × 35 = 280
B. 5 + 3 × 35 = 5 + 105 = 110 (not equal to 8 × 35)
C. (8 × 30) + (8 × 5) = 240 + 40 = 280
D. (8 + 30) × (8 + 5) = 38 × 13 = 494 (not equal to 8 × 35)
E. 8 × (20 + 15) = 8 × 35 = 280
Therefore, the expressions that are equal to 8 × 35 are A, C, and E.
