Multiplier Calculations of Brian’s Math Facts Acquisition

Measure Multiplier Formula Target A to Target B Multiplier Calculation Target A to Target B Multiplier Value Target A to Target B
Celeration Divide the larger celeration by the smaller celeration and show the sign of change. (×3.0) ÷ (×1.5) ×2.0
Base frequency Divide the larger base frequency by the smaller base frequency and show the sign of change. (28) ÷ (16) ×1.75
Bottom frequency Divide the larger bottom frequency by the smaller bottom frequency and show the sign of change. (28) ÷ (14) ×2.0
Top frequency Divide the larger top frequency by the smaller top frequency and show the sign of change. (56) ÷ (50) ×1.12
Bounce Divide the larger bounce by the smaller bounce and show the sign of change. (×1.8) ÷ (×1.2) ÷1.5
