5-Minute Math Power Drill: Algebra & Arithmetic

Ready to sharpen your speed? This drill is designed to be repeated until the logic becomes second nature. No calculators—just your brain and the clock.

1. The BIDMAS Trap (Arithmetic) #

Precision matters more than speed here. Remember: Indices come before multiplication, and Multiplication happens before that final subtraction.

The Logic: Calculate: $12 - 2 \times (4 + 1)^2$

1.

Brackets first:

(5)^2 = 25

2.

Multiply next:

2 \times 25 = 50

3.

Subtract last:

12 - 50 = -38

Fill in blanks

2. The Negative Sign Pivot (Algebra) #

Expanding brackets is where most students drop easy marks—usually because they forget that a negative outside the bracket flips the signs inside.

The Logic: Expand $3(2x + 1) - 2(x - 4)$

1.

First part:

6x + 3

2.

Second part (the pivot):

-2x + 8

(Watch that

+8

!)

3.

Result:

4x + 11

Single choice

3. Two-Step Isolation (Equations) #

Your goal is to strip away the numbers surrounding $x$ using inverse operations. Do it in the reverse order of BIDMAS: deal with the addition/subtraction first.

The Logic: Solve $3x + 5 = 17$

1.

Remove the constant:

3x = 12

2.

Isolate the variable:

x = 4

Coach Javi's Tip: If this took you longer than 4 minutes, reset the timer and try again tomorrow. We're aiming for under 180 seconds for a perfect score.
