title: Why doesn't there exists a subi opcode for MIPS?
body: <p>I am very new to <strong>Assembly language</strong>. I was reading about <strong>MIPS</strong> architecture and came to know that you have <code>addi</code> opcode but there is no <code>subi</code> opcode. Why don't we have a <code>subi</code> opcode?</p>
