Multiply faster

Multiply any two numbers in a single line

Long multiplication means stacking partial products and adding them up — slow and error-prone under time pressure.

Spot it when

Any two numbers that are not near a round base and not full of 9s — the everyday case.

e.g.43×2743 \times 27

Set up Vertical & Crosswise

Write 23 and 14. We will compute column by column: vertical (same position) and crosswise (crossing positions).

When you’ll actually hit this

Real moments — exams, homework, competitions — where this shortcut earns its keep.

Competition

A timed mental-maths round gives you 30 two-digit multiplications in 5 minutes — no rough paper allowed.

becomes76×8376 \times 83

Vertically & crosswise in one pass: 6308 — no partial products written down.

Homework

You are checking a physics answer that needs 23 × 14 and the calculator is packed away.

becomes23×1423 \times 14

Units 3×4=12 (2, carry 1), cross 2·4+3·1=11 +1=12 (2, carry 1), tens 2×1=2 +1=3 → 322.

In class

Three-digit multiplication on a board sum in class, and the teacher wants it without a grid.

becomes123×456123 \times 456

The crosswise "diamond" gives every digit in one sweep → 56088.

Real life

Stock check at a shop: 24 cartons of 16 units each — total stock in your head.

becomes24×1624 \times 16

Crosswise: 2·1=2 | 2·6+4·1=16 | 4·6=24 → carry through → 384.

The method behind it

Vertically and crosswise

Multiply digits vertically, then crosswise, then vertically again — the pattern forms an expanding diamond.

Conventional: 43×27=43×20+43×7=860+301=116143\times 27 = 43\times 20 + 43\times 7 = 860+301 = 1161 (2 partial products + addition). Urdhva: 4×2=84\times 2=8, 4×7+3×2=344\times 7+3\times 2=34 (3 carry 3), 3×7=21+3=2411613\times 7=21+3=24 \to 1161 (simultaneous mental computation).

Works for any digit count. Single mental pass with carries, no partial products written.

Use when

  • Any two numbers — this is the universal method

Avoid when

  • Numbers very close to a base (Nikhilam is faster there)
