Kui lugeda kokku alumised koos olevad ruudud, saame vastuse esimeseks numbriks A.
for ( var i = 0; i < A; i++ ) {
label( [10.5 * i + 5, 5], "\\large{\\mathbf{100}}", { color: "black", background: "#a2bff4" } );
}
Because there are no tens blocks, the tens digit of the number is 0.
Kui lugeda kokku koos olevad ruudud, saame vastuse esimeseks numbriks B.
for ( var i = 0; i < B; i++ ) {
label( [5, -1.5 * i - 0.6], "\\large{\\mathbf{1\\:0}}", { color: "black" } );
}
Because there are no single unit blocks, the units digit of the number is 0.
Kui lugeda kokku eraldi seisvad ruudud, saame vastuseks C.
for ( var i = 0; i < C; i++ ) {
label( [1.5 * i + 0.5, 0.5], "\\mathbf{1}", { color: "black" } );
}
Seega on pildil kokku N ruutu.
