A Peek Inside the Lesson
This is the real lesson text your child hears, read aloud by a friendly voice.
An equation is like a balance: both sides are equal. x + 7 = 15 asks what number plus 7 is 15.
Undo with the opposite operation: subtract 7 from both sides, x = 8.
For 4x = 28, the opposite of multiplying by 4 is dividing by 4: x = 7.
Always check: put your answer back in. 4 × 7 = 28. Correct!
