Where do you put the parenthesis to get the correct answer?
20 - 4 + 3 x 3 = 25
Pregunta 5
Pregunta
Where do you put the parenthesis to get the correct answer?
7 + 2 x 6 + 3 ÷ 3 – 7 = 6
Respuesta
-
7 + 2 x (6 + 3) ÷ 3 – 7 = 6
-
7 + 2 x 6 + (3 ÷ 3) – 7 = 6
-
(7 + 2) x 6 + 3 ÷ 3 – 7 = 6
Pregunta 6
Pregunta
Is the solution correct?
3 + (9/9) x 50 - 2 = 50
Pregunta 7
Pregunta

90 + 18 / 9 = ?
[blank_start]___[blank_end] + [blank_start]___[blank_end] = [blank_start]___[blank_end]
Pregunta 8
Pregunta
Solve by filling in the blanks.
30 − 2 − 7 × 2
= [blank_start]___[blank_end] - [blank_start]___[blank_end] - [blank_start]___[blank_end]
= [blank_start]___[blank_end] - [blank_start]___[blank_end]
= [blank_start]___[blank_end]

Pregunta 11
Pregunta
Solve by filling in the blanks.
6 + (45 / 5) + (6 x 3) = ?
6 + [blank_start]___[blank_end] + [blank_start]___[blank_end] = ?
[blank_start]___[blank_end] + [blank_start]___[blank_end] = [blank_start]___[blank_end]

52 - 28 / 7 - 4 x 2
= [blank_start]____[blank_end] [blank_start]__[blank_end] [blank_start]____[blank_end] [blank_start]__[blank_end] [blank_start]____[blank_end]
= [blank_start]____[blank_end] [blank_start]__[blank_end] [blank_start]____[blank_end]
= [blank_start]____[blank_end]
Pregunta 14
