What is an Input\/Output Table?<\/strong><\/p>\n\n\n\n

It is a table that shows numbers going in<\/strong> (input) and numbers coming out<\/strong> (output) after a rule is applied.<\/p>\n\n\n\n

For subtraction, the rule is \u201csubtract a number\u201d<\/strong>.<\/p>\n\n\n\n

Parts of the Table:<\/strong><\/p>\n\n\n\n

Input:<\/strong> The starting number.<\/p>\n\n\n\n

Rule:<\/strong> Tells us what to do (e.g., subtract 2).<\/p>\n\n\n\n

Output:<\/strong> The result after subtracting.<\/p>\n\n\n\n

Example Table (Subtract 3):<\/strong><\/p>\n\n\n\n

Input<\/th>Rule<\/th>Output<\/th><\/tr><\/thead>
10<\/td>subtract 3<\/td>7<\/td><\/tr>
12<\/td>subtract 3<\/td>9<\/td><\/tr>
15<\/td>subtract 3<\/td>12<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Steps to Use the Table:<\/strong><\/p>\n\n\n\n

Look at the input number<\/strong>.<\/p>\n\n\n\n

Check the rule<\/strong> (what to subtract).<\/p>\n\n\n\n

Subtract<\/strong> the number from input \u2192 get the output<\/strong>.<\/p>\n\n\n\n

Practice Tip:<\/strong><\/p>\n\n\n\n

Start with numbers up to 18.<\/p>\n\n\n\n

Check your answer by doing Output + Subtracted Number = Input<\/strong>. \u2705<\/p>\n\n\n\n

Why It\u2019s Important:<\/strong><\/p>\n\n\n\n

Helps to see patterns<\/strong> in subtraction.<\/p>\n\n\n\n

Makes solving problems faster and easier<\/strong>.<\/p>\n\n\n\n

Strengthens mental math skills<\/strong>.<\/p>\n\n\n\n

Fun Tip with Emojis \ud83c\udfa8:<\/strong><\/p>\n\n\n\n

Input \ud83d\udfe2 \u2192 Subtract \u2796 \u2192 Output \ud83d\udd35<\/p>\n\n\n\n

Example: \ud83d\udfe210 \u2796 3 = \ud83d\udd357<\/p>\n\n\n\n
